Sulfation in lead acid batteries? (TOP 5 Tips)

Sulfation is the formation or build-up of lead sulfate crystals on the surface and in the pores of the active material of the batteries’ lead plates. During normal use of the battery the formation of lead sulfate crystals is only temporary, they disperse during the recharging process.

  • Sulfation occurs in lead–acid batteries when they are subjected to insufficient charging during normal operation. It impedes recharging; sulfate deposits ultimately expand, cracking the plates and destroying the battery. Eventually, so much of the battery plate area is unable to supply current that the battery capacity is greatly reduced.

What causes sulfation in a lead acid battery?

Sulfation happens inside Lead–acid batteries when the electrolyte starts to break down. As the sulphuric acid (electrolyte) splits up, sulfur ions become free forming crystals. These sulfur ion crystals then stick to the lead plates of the battery, thus forming lead sulfate crystals.

How do you remove sulfation from a lead acid battery?

Fill the lead-acid battery cells up to the maximum marker using distilled water. Leave the cell covers off. You will heat the plates during the recharge process, which will help dissolve the sulfation.

Can you fix a sulfated battery?

Reversible sulfation can often be corrected by applying an overcharge to an already fully charged battery in the form of a regulated current of about 200mA. The battery terminal voltage is allowed to rise to between 2.50 and 2.66V/cell (15 and 16V on a 12V mono block) for about 24 hours.

How do you know if a battery is sulfated?

The most common sign of a sulfated battery is one that will not charge very well, or simply refuses to charge at all. If you suspect your electronic accessories are not receiving enough amperage (weak a/c, dim headlights) it is a strong sign that your battery is sulfated.

How long should you Desulfate a battery?

Depending on the size of the battery, the desulfation process can take from 48 hours to weeks to complete. During this period the battery is also trickle charged to continue reducing the amount of lead sulfur in solution.

What is meant by sulfation?

[ sŭl-fā′shən ] n. The addition of sulfate groups as esters to molecules.

How does Epsom salt Desulfate a battery?

Sulfation happens when the solid lead sulfate builds around the battery plates inside. Epsom salt or Magnesium sulfate solution is capable of softening these solid salts.

How do you dissolve lead sulfate?

Lead(II) sulfate can be dissolved in concentrated HNO3, HCl, H2SO4 producing acidic salts or complex compounds, and in concentrated alkali giving soluble tetrahydroxidoplumbate(II) [Pb(OH)4]2 complexes. Lead(II) sulfate decomposes when heated above 1000 °C: PbSO4(s) → PbO(s) + SO.

Will a trickle charger Desulfate a battery?

Fact #2: This is not true! Batteries develop a high resistance to charging which the average (so-called) smart charger cannot overcome. However, not every ‘dead’ battery can be desulfated and neither can a desulfated battery be recovered to 100% of its previous ability.

Does battery Tender Plus Desulfate?

The Battery MINDer 1215C can maintain up to four batteries at a time, according to the manufacturer, and it features an automatic full-time desulfation function to remove sulfate crystal build-up and extend battery life.

What is a Sulfated Battery and How to Prevent It

It is the most common cause of early battery failure in lead-acid batteries, and it is caused by an accumulation oflead sulfatecrystals. ASulfatedbattery is the most common cause of early battery failure in lead-acid batteries. Batteriesulfation may cause significant harm, yet it is readily avoidable and, in certain situations, can even be repaired. Continue reading to find out more about battery sulfation and how to avoid it in the future.

How does battery sulfation occur

An overgrowth of lead sulfate crystals in an acid battery is the leading cause of early battery failure in lead-acid batteries. ASulfatedbattery is characterized by a buildup of lead sulfate crystals in an acid battery. Batteriesulfation can cause significant harm, although it is readily avoidable and, in certain situations, reversible. More information about battery sulfation and how to avoid it may be found in the following sections.

  • Battery life is substantially reduced, and the battery may completely fail due to prolonged charging periods, severe heat build-up, and shorter running hours between charges.

What Causes sulfated batteries

Sulfation will accumulate in all lead-acid batteries over the course of their lifespan since it is a natural byproduct of the battery’s natural chemical process. Sulfation, on the other hand, accumulates and produces issues when;

  • A battery that has been overcharged
  • A battery is kept above 75 degrees Fahrenheit. When a battery is not fully charged, it is stored.

how to reverse battery sulfation

When it comes to lead batteries, there are two forms of sulfation that can occur; the first is reversible, while the second is permanent. Their names accurately describe the effects they have on your battery. It is feasible to reverse the sulfation of a battery if the problem is identified and addressed quickly enough. While this may be done by anybody, it should only be done by someone who has previous expertise working with lead batteries, such as the retail location where your battery was originally bought.

Permanent Sulfation

When a battery has been in a low state of charge for several weeks or months, it is said to have suffered from permanent sulfation. While things can occasionally be saved, it is doubtful that they will be able to be restored in their entirety.

Reversible Sulfation

Sulfation may frequently be reversed by delivering an overcharge to a battery that has previously been completely charged, often in the form of a controlled currentof around 200mA. For approximately 24 hours, the battery terminal voltage is permitted to grow to between 2.50 and 2.66V/cell (15 and 16V on a 12V mono block), depending on the battery type. Increasing the temperature of the battery to 50–60°C (122–140°F) during the corrective service can aid in the dissolution of the crystals even more.

How to prevent Battery sulfation

Proper battery storage is one of the most straightforward methods of avoiding battery sulfation. When a battery is stored, even if it is stored at full charge, the battery must be sufficiently charged to keep it from decreasing below 12.4 volts throughout the storage process. The use of this maintenance charge will avoid the accumulation of sulfates. Also worth noting is that, while we previously said that batteries should not be stored at temperatures higher than 75 degrees, the rate of self-discharge increases by a factor of ten for every 10 degrees over room temperature.

It is sufficient to perform routine battery maintenance and to adhere to industry-standard charging standards.

Once sulfation of the lead plates has happened, it is extremely rare that the consequences will be reversed, making it vital to take good care of your batteries from the beginning.

BU-804b: Sulfation and How to Prevent it

Sulfation happens when a lead acid battery is not given a complete charge for an extended period of time. This is a typical problem with starting batteries in automobiles that are driven in the city and have accessories that draw a lot of power. A motor running at idle or at a low speed will not be able to adequately charge the battery. Electric wheelchairs suffer from a similar difficulty in that the users may fail to charge the battery for an adequate amount of time. When the chair is not in use, an 8-hour charge over the night is not sufficient.

  1. This might explain why wheelchair batteries have a lifespan of only two years, yet golf vehicles with the same battery have a lifespan that is twice as long as the wheelchair battery.
  2. Typically, this occurs in rural areas of the world when residents consume large quantities of electricity while having limited access to renewable energy sources to recharge the batteries.
  3. Only a periodic completely saturated charge will be able to resolve the issue.
  4. The use of lithium-ion batteries, which prefer a partial charge rather than a full charge, is an additional method to consider.
  5. Because of the longer service life, it is claimed that the cycle count is less expensive than that of lead acid, despite the fact that it is more expensive.
  6. Small sulfate crystals may develop during usage, but this is completely natural and poses no health risk.
  7. This results in the formation of big crystals, which in turn reduces the amount of active material in the battery, which is responsible for its performance.

If a battery is serviced early, reversible sulfation can often be corrected by applying an overcharge to a fully charged battery in the form of a regulated current of about 200mA to a fully charged battery that has already been fully charged.

Increasing the temperature of the battery to 50–60°C (122–140°F) during the corrective service can aid in the dissolution of the crystals even more.

At this point, it appears that no type of restoration is feasible; yet, the yield of recovery is not completely known.

Other considerations may be relevant.

A fully charged battery that retains a stable voltage profile on discharge has a better chance of reactivation than a battery that drops rapidly with load due to a loss of charge.

These devices apply pulses to the battery terminals in order to prevent and reverse sulfation.

A “one size fits all” approach is used, and the method is unscientific in its application.

There are no simple methods for measuring sulfation, and there are no commercial chargers that apply a calculated overcharge in order to dissolve the crystals in solution.

While anti-sulfation devices can help to reverse the condition, some battery manufacturers do not recommend using them because they can cause soft shorts in the battery, which can lead to increased self-discharge.

When charging lead acid batteries, battery manufacturers specify the amount of ripple that is permitted.

Sulfation in lead–acid batteries

For the most part, all military land vehicle systems rely on a lead–acid battery to start the engine when the vehicle is moved. This battery’s maintainability and, consequently, system readiness have degraded as a result of a lack of understanding about the reasons for battery failure. Sulfation is frequently used to describe the performance deterioration of lead–acid batteries, and it is the phrase that is most frequently heard to describe this phenomenon. Sulfation is a leftover word that first appeared in the context of lead–acid battery development during the early stages of the technology’s development.

The term “sulfation” is only used in the context of a larger user community, and it has spawned a plethora of cures for dealing with sulfation issues over time as a result.

Additionally, mechanistic models are required for a clear understanding of the operation and optimal utilization of this battery system.

Blog – How To Diagnose and Treat Battery Sulfation

Battery sulfation refers to the process of lead sulfate crystals accumulating on the surface of a battery cell over time. Sulfation will occur to some extent in every battery during the course of its useful life span. Rapid sulfation, on the other hand, can occur as a result of prolonged storage, overcharging, or undercharging of a battery. The more sulfate accumulates on a battery cell, the less effective the battery becomes as a result of the accumulation. When it comes to lead-acid batteries, sulfation is the most common cause of early failure.

How can I prevent battery sulfation?

It is simple to avoid battery sulfation, which will allow you to save money and time by extending the life of your battery. Please take into consideration the following recommendations to avoid severe battery sulfation: Charge your lead-acid battery on a regular basis, ensuring that it receives a full charge whenever feasible, and avoid leaving batteries depleted and unused for extended periods of time. The NOCO Genius G7200 7.2A Smart Charger, which is seen on the left, is the ideal tool for keeping your battery in good working order.

Provided you feel that your battery is sulfated, it is still possible to restore your battery if the problem is identified and handled as soon as feasible.

How Can I Diagnose My Battery As Sulfated?

If you have been the victim of a sulfated battery, you will begin to see the indicators of decreased efficiency immediately after installation. Sulfated batteries are most commonly identified by their inability to charge properly or by their complete inability to charge in the first place. If you have reason to believe that your electrical accessories are not receiving enough current (poor air conditioning, dim headlights), this is a clear indication that your battery is sulfed. In the event that your battery dies before you anticipate it to, there’s a strong likelihood that it was caused by sulfation.

  1. Your battery is undercharged if it has a voltage of less than 12.6 volts.
  2. There is also the option of doing a visual sulfation diagnostic test on the cells of your battery if necessary.
  3. Using a flat head screwdriver, carefully pry off the caps on the battery’s top and remove the battery.
  4. A typical sulfated battery will have cells and separators that are gray and dirty, and they will be difficult to differentiate from one another in appearance.
  5. Sulfation in a battery can be visually identified using the graphic representation shown below.

Sulfation in Lead Acid Batteries – A phenomenon less understood!

When a cell or battery is drained, lead sulfate is generated on both the positive and negative plates of the cell or battery. It is during the subsequent charging process that this sulfate is transformed into active components. The sulfation of a lead acid battery is an unavoidable element of the process of the battery’s functioning. It is composed of uniformly distributed tiny crystals that create a porous mass that is extremely conductive and emerges when a normal discharge state is encountered.

Observations have revealed that the active material of the plates is virtually fully transformed into lead sulfate in such situations as these.

Such sulfation, which has developed as a result of neglect or overuse of the battery, has the potential to inflict permanent harm to its plates.

  • A battery is left in a discharged state for an extended length of time
  • A battery is topped up with acid rather than water
  • A battery is repeatedly over discharged
  • And so forth. It is necessary to run a battery at increased temperatures — above and above the authorized safe operating limits
  • A battery is not treated to or repaired in a timely manner as soon as it is discovered that one or more of its cells is experiencing performance issues
  • A battery that has been undercharged over an extended period of time
  • A battery with inadequate electrolyte in the cells as a result of insufficient topping up

The following are the indications of sulfation of the plates:

  • Cell or battery capacity decrease
  • Gassing begins much earlier in the charge cycle
  • An abnormal color on the positive plates – light brown with white spots
  • A very low specific gravity of acid
  • An increase in the volume of the negative plates with significant bulging
  • And a decrease in the capacity of the cell or battery.

There are several techniques for reviving sulfated batteries, including the following: Using one of the ways involves draining the electrolyte from the cells and instantly refilling the battery with water. Allowing for a little resting period of approximately an hour or two will allow this water to percolate into the plates, after which you may begin charging at a very low current rate. Make certain that the temperature does not rise while the current is increased in stages and repeated repeatedly.

  1. gr.) will rise.
  2. After a period of continuous charging, the final specific gravity generally stabilizes at a value that is somewhat lower than the target value.
  3. The preceding procedure may normally be completed by the battery manufacturer or under the supervision of an expert alone.

Avoid Battery Sulfation with a BatteryMINDer Battery Charger

Batteries will not sulfate, according to many charger manufacturers, provided a battery is constantly maintained fully charged, according to another. This is completely false. What is Battery Sulfation, and how does it occur?

Sulfation, which is the accumulation of lead sulfate crystals, is the most common cause of early failures in lead-acid batteries, whether they are sealed AGM or flooded (wet cell-filler caps). The use of a sulfated battery might result in the following consequences:

  • Several battery charger manufacturers assert that if a battery is kept fully charged at all times, sulfation will not occur. Unfortunately, this is not accurate. The term “Battery Sulfation” is defined as follows: A build-up of crystals of lead sulfate is the most common cause of early failures in lead-acid batteries, whether they are sealed AGM batteries or flooded (wet cell-filler caps). Following are some of the consequences of using a sulfated battery:

Other factors that contribute to battery failure include vibration, contaminants, broken charge plates (due to overheating), and under or overcharging of the battery cell. What is the root cause of a sulfated battery? During the course of their useful lives, all lead-acid storage batteries will acquire sulfate. This covers the modern sealed “dry” types such as the Optima, Odyssey, Exide, and Interstate branded AGM-spiral-wound types as well as the older AGM-spiral-wound varieties. Each time a battery is used, sulfation develops in the battery (discharged – recharged).

  • Even if a battery is completely charged when it is kept, sulfate will accumulate unless a desulfating battery charger is used to charge the battery.
  • In fact, for every 10°F increase over room temperature, the discharge rate and sulfation increase by a factor of two.
  • High frequency electrical pulses can be used to safely recover a sulfated battery to its original condition (NOT high voltage).
  • In this way, it is certain that both old and newly produced battery sulfation will be safely removed in the shortest period feasible.
  • What Is It About the BatteryMINDer ®Desulfation Method That Is So Special?

Due to the fact that we only generate the frequencies that are required and avoid using excessive voltages, we can avoid the possible damage to the batteries’ storage plates, which is known as “flaking.” Sulfuric acid, which is the primary constituent of a sulfate crystal, may thus readily enter into the electrolyte solution (liquid, gel or absorbed type).

It does this in the shortest amount of time feasible while avoiding the development of excessive heat.

If you test your battery for sulfation, you will learn more about the status of your battery than you would ever learn from any “anecdotal” history.

Battery sulfation should never be a problem because of BatteryMINDers’ TM capacity to fully charge batteries without ever overcharging them, no matter how long they are kept attached.

Following is a list of the questions you should be posing to yourself:

  • Do I want my batteries to last as long as possible (5+ years)
  • Do I want the highest level of performance during their lifetime
  • Do I want them to charge as quickly and safely as possible
  • Do I want to eliminate or greatly reduce battery maintenance (adding water, etc.)
  • Do I want to use the least amount of electricity to charge my batteries
  • Do I want to recoup the cost of the charger before I have to replace the battery for which it was purchased? Do I want to recoup the cost of the charger before I have 1

A desulfating battery charger is required if any of the above questions are answered affirmatively by the user. Do not forget about the 100 percent money back guarantee, as well as the five-year “no fuss,” 100 percent parts and labor or complete replacement warranty on BatteryMINDers TM. Suppose you started with a new battery that cost between $85 and $150, and that you followed the BatteryMINDer ®’s directions to the letter.

3 Things to Know About Battery Sulfation

An car is reliant on two distinct but equally vital energy sources: gasoline and electricity. In the first place, gasoline supplies the energy required to run your engine and propel your wheels forward. Your car battery is responsible for two things: first, it delivers the electrical energy required to power everything from your headlights to your radio and even your phone charger. Your automobile will not even start if the battery is not in good operating order. Automotive batteries have been carefully developed by manufacturers to recharge while you are driving your automobile.

Sulfation is a relatively unknown but all-too-common condition that affects many people.

  1. Sulfation is responsible for a large number of early battery failures.

The presence of sulfation in a battery might explain why it failed to perform as expected before its intended lifespan. Sulfation is one of the most prevalent causes of early failure in lead-acid automobile batteries. Even before it causes your battery to completely fail, sulfation has an adverse effect on your vehicle in a variety of ways that can be quite detrimental. Sulfation is the production of lead sulfate crystals on the surface of the battery’s plates as a result of the action of the acid.

  • However, when the deposits increase in size, they have the effect of reducing the amount of active material contained within your battery.
  • A battery that has suffered from sulfation will have a considerable reduction in cranking power when turned on.
  • Sulfation also raises the likelihood of a boil over, which occurs when the acid in the battery boils and spills out of the battery.
  • Almost any of these factors might cause a car battery to fail earlier than intended.
  • Almost every time your battery is used, little quantities of sulfate crystals are formed.
  • One of the most prevalent causes of sulfation is batteries that are left permanently undercharged for an extended period of time.
  • On a purely chemical basis, undercharging makes the formation of sulfate crystals far more straightforward.
  • It is not need to be concerned with sulfation as much if you routinely travel by automobile on the highway, as opposed to driving in urban areas.

That extra time on the road at faster speeds allows the alternator enough time to recharge your battery completely. City drivers, on the other hand, are at a far higher risk of sulfation since the shorter stop-and-go driving frequently fails to fully charge your vehicle’s battery.

The chemical change that results in sulfation can also occur in the opposite direction. Sulfates are formed as a result of the operation of your battery. While your battery is being charged, a chemical reaction called as gassing takes place, causing the sulfates to escape. As a result of gassing, the lead sulfate crystals revert to their original state of sulfuric acid and lead. Eventually, when sulfation progresses, which is frequently the result of a persistently undercharged battery, reversing the process becomes increasingly difficult for your alternator to achieve on its own.

A battery desulfator removes even the most stubborn sulfate deposits from your battery by exposing it to bursts of extremely high voltage.

Here’s Why Sulfation Is Bad News for Your Battery

During the course of diagnosing the early failure of your vehicle’s lead-acid battery, technicians will come across a condition known as sulfation. The fact that this is a widespread problem does not rule out the possibility that you are unaware of it. Understanding the ABCs of sulfation will assist you in comprehending the explanation of occurrences provided by your specialist. In addition, it will assist you in understanding how you may prevent the problem from occurring again in the future.

How Lead-Acid Batteries Work

Before delving into the specifics of sulfation, it’s important to understand the fundamentals of how lead-acid batteries work. The lead plates in the inside of this sort of battery are surrounded by a sulfuric acid solution, which serves as the battery’s acid. Half of the plates, which are constructed of a substance known as lead peroxide, are electrically charged in the positive direction. Negatively charged plates constructed from a substance known as sponge lead are used in conjunction with these.

First, crystals of a chemical known as lead sulfate are formed on both the positive and negative plates of the instrument.

When the level of lead sulfate generation reaches its maximum, the battery depletes its whole charge.

Sulfuric acid solution is re-charged using lead sulfate crystals that dissolve throughout the recharging process.

What Is Sulfation?

Sulfation is the word used to describe the development of lead sulfate on the lead plates of your battery’s lead plates. This accumulation occurs on a regular basis, every time your battery is used. You could question, why is sulfation an issue if it occurs on a regular basis, right? It has been discovered that the sulfation process operates on two levels. The formation of lead sulfate crystals in your battery occurs only temporarily during regular operation of your battery.

Rather of being fixed in situ, the crystals dissipate throughout the recharging cycle of the battery. When the covering of lead sulfate becomes persistent and does not wash away, sulfation problems begin to manifest themselves.

Consequences of Permanent Sulfation

In a lead-acid battery, permanent sulfation can cause a variety of issues, including corrosion. The list of these issues includes a significantly decreased battery lifespan as well as complete battery failure. It also contains the following items:

  • A significant increase in usual charging times
  • A reduction in starting power
  • And Temperatures within your battery that are abnormally high
  • The necessity of recharging your battery on a more frequent basis

Permanent sulfation in lead-acid batteries is widely acknowledged as the most common cause of early failures in this kind of battery.

How Does the Problem Occur?

When it comes to battery sulfation, there are several different possibilities regarding what’s going on. Known reasons include, for example, the following:

  • The length of time that passes between battery recharging cycles is excessive. Battery that has been recharged but has less than 100 percent capacity after being discharged Recharging equipment that has been configured incorrectly
  • Inadequate levels of sulfuric acid solution in a battery’s internal electrolyte solution The exposure of lead battery plates to the atmosphere. Batteries are used for long-term storage without access to an energy source.

If you regularly leave your vehicle running at idle, you increase the likelihood of recharging to less than 100 percent. The excessive usage of power-hungry car plug-ins might also contribute to the same problem as described above.

Preventing and Addressing Permanent Sulfation

Regular maintenance of your lead-acid battery is, without a question, the most effective method of avoiding irreversible sulfation. For a battery to be safe from sulfation during storage, it must be charged to at least 12.4 volts at all times. Additionally, you should avoid keeping a lead-acid battery in an area that is hotter than 75 degrees Fahrenheit. This is due to the fact that every ten-degree increase in temperature over that point causes the discharge rate of stored batteries to double.

  • This is not always the case.
  • A battery that has been seriously damaged, on the other hand, may never recover.
  • You have a battery that has been harmed by the signs of residual sulfur contamination.
  • You may be fortunate enough to get the problem resolved by a professional recharging.
  • Having the knowledge that you have options while looking for the best power source is beneficial.
  • Powetron Battery Co., on the other hand, provides all of the alternatives you’ll require at the most competitive prices.

Images courtesy of Jupiterimages/ Images Whenever lead-acid battery plates are exposed to air or when the specific gravity of the battery falls below 1.225, sulfation occurs, which is a normal chemical reaction. During the process of sulfation, soft lead sulfate, which is a mixture of lead and sulfur, undergoes cystalization and becomes hard lead sulphate. As a result, the battery cells are unable to maintain an electrical charge, and the battery eventually dies.

If the sulfation has progressed too far, it will be impossible to remove it from the lead plates; however, if it has only recently begun to develop, it will be possible to remove it by gradually recharging the cells.

Step 1

Check the fluid level in the lead-acid battery cells to ensure they are fully charged. Using your fingers or a flat-head screwdriver, detach the cell covers from their mountings and remove them.

Step 2

Check to see if the fluid level in the cell is lower than the minimum marker on the side of the container. You can most likely see that the lead plates have been exposed. Sulfation is seen when hard lumps of crystals are visible on the plates and around the cell walls, indicating that the cells have been sulfated. While a gradual recharge may be necessary in some cases, if the cystalization is not covering the walls and the plates only contain minor deposits, you may be able to remove all of the sulfation.

Step 3

Fill the lead-acid battery cells with pure water until they reach the maximum capacity marking. Remove the covers from your cell phones. During the recharge process, you will be heating the plates, which will aid in the dissolution of the sulfation.

Step 4

Assemble the lead-acid battery terminals by connecting the two battery cable clamps from the battery charger to them. The “+” connector is connected to the red wire, and the “-” terminal is connected to the black cable.

Step 5

Set the charge rate of your battery charger to the lowest possible setting. Charge your lead-acid batteries slowly and over an extended period of time, and the more probable it is that the sulfation will be eradicated.

Step 6

Turn on the battery charger if you have one. Charge your lead-acid battery for 6 hours before opening it up and inspecting the interior of the battery cells. Don’t forget to keep your charger charged. Small bubbles rising to the surface of each cell are a positive indicator that your battery cells are charging, and you should keep an eye out for them. The sulfation begins to dissolve as a result of the charging process. If you are unable to notice bubbles rising in a certain cell, it is possible that the cell is unable to recharge; nonetheless, you should wait until the whole charge period has been completed.

Step 7

Continue to charge the battery for at least another 18 hours at a minimum rate. Check the cells once again, but don’t switch off the charger just yet. If the cells are taking up the charge, they should be releasing bubbles at a quick pace. If any of the cells does not begin to produce bubbles by this time, the cell will not be able to recover. You will need to acquire a new battery to complete the task.

Step 8

Make contact with the side of the battery with your hand. It will be comfortable and warm, which is a wonderful thing. The heat and bubbles are working together to remove the sulfation from the lead plates. Allow your battery to charge for a further 6 hours before using it. Remove the charger from the wall. Remove the battery-cable clamps from the battery terminals that were attached to the charger. Replace the covers on the cells with new ones. ReferencesTips

  • If you need to fill the cells in your battery, never use tap water since it includes minerals that are harmful to the cells.

What You’ll Need to Get Started

  • Protective gloves and goggles are required, as is distilled water and a lead-acid battery charger.
  • Make certain that you are wearing protective gloves and eyewear. If sulfuric acid splashes into your skin or into your eyes, it will burn your skin and may cause you to go blind.

When you attempted to start your vehicle, you heard the dreadedclick, click, clicksound that indicates a dead battery. Your battery has been destroyed by a build-up of sulfation, but what exactly is sulfation? Batteries are similar to live beings in that they require activity and upkeep in order to avoid “dying.” Lead-acid batteries are used in the majority of automobiles. Lead-acid batteries, which were first used in 1859, are considered to be one of the first forms of rechargeable batteries.

  • A lead-acid battery has a high power density, which means it is capable of discharging huge quantities of energy in a short period of time.
  • Lead-acid batteries are made up of a number of individual cells.
  • Cells are tightly packed with lead and lead oxide sheets that alternate with one another.
  • When a battery is used, the sulfuric acid in the electrolyte is drained, and the battery must be recharged.
  • As this is taking place, sulfate from the acid is coating the plates, reducing the amount of surface area available for a chemical reaction to take place.
  • Sulfation, a buildup of lead sulfate crystals in the battery, is the most prevalent cause of battery failure.
  • Sulfate compounds precipitate on the discharged parts of the battery plates, causing the battery to get damaged and eventually fail.

It is the accumulation of sulfation that causes the issues.

How to Restore Sulfated Batteries

With the use of high frequency electrical pulses, sulfation (pronounced sul-fay-shun), the number one cause of early battery failures, may be safely reversed. Unlike other pulse type battery chargers that promise this or similar sounding qualities, VDC’s BatteryMINDers® employ a spectrum of high frequencies to charge the batteries they are charged with. This assures that both old and freshly produced sulfation will be safely dissolved in the shortest amount of time feasible after formation. Using a single set frequency may be effective in removing certain sulfate crystals, but not all, especially those that have been in place for a long time.

  • It is more accurate to say that they “dissolve” the sulfate rather than “destroying” or shaking it away.
  • This quickly increases the specific gravity of the solution and allows the storage plates to take a greater amount of charge.
  • There is no loss of electrolyte during this process, ensuring that sealed batteries, as well as “wet” batteries, will never expire as a result of electrolyte loss.
  • Several battery charger manufacturers say that if a battery is kept fully charged at all times, it will not suffer sulfation.
  • During the course of their useful lives, all lead-acid storage batteries will acquire sulfate.
  • Each time a battery is used (discharged and recharged), sulfation develops in the battery.
  • It is possible that this issue will worsen when using smaller lead acid batteries, such as motorbike batteries.
  • A sufficient charge must be applied to prevent the battery’s voltage from going below 12.4 Volts* (2.07 volts per cell).
  • In fact, for every 10 degrees Fahrenheit increase over room temperature, the discharge rate and sulfation increase by a factor of two.

A Manufacturers’ 100 percent Money Back Guarantee as well as a 5-year “no fuss” comprehensive warranty are provided by VDC Electronics to ensure that BatteryMINDers’ patent** process is the most effective available.

Here are the questions you should be asking yourself:

  • Do I want my batteries to last as long as possible (5+ years)
  • Do I want the highest level of performance during their lifetime
  • Do I want them to charge as quickly and safely as possible
  • Do I want to eliminate or greatly reduce battery maintenance (adding water, etc.)
  • Do I want to use the least amount of electricity to charge my batteries
  • Do I want to recoup the cost of the battery charger before I have to replace the battery for which it was purchased? Do I want to win back the cost of the battery charger before I ***

If you responded yes to any of these questions, you are in need of a desulfating charger-maintainer to keep your system running well. Also keep in mind that the Manufacturer ensures its performance with a 100 percent Money Back Guarantee in addition to a five-year “no fuss,” 100 percent parts and labor or full replacement warranty. * When kept at room temperature. Applies to 12-volt batteries or two 6-volt batteries linked in series.**U.S. Patent No. 6078166*** Assume you started with a new battery that cost between $85 and $150 and lasted at least twice as long as it would have if you hadn’t desulfated it in the first place.

It is a normal and essential element of a battery’s life cycle, and it happens whenever the battery is in a state of discharge, that is, when the battery is not being charged. As the battery declines over time, the electrolyte solution inside the battery dissolves into water, and the lead plates get coated with lead sulfate crystals, which eventually cause the battery to fail.

  1. However, depending on usage, the average battery life ranges from six to 48 months, with just 30 percent of all batteries reaching the 48-month mark in total.
  2. During the course of normal use or when a battery is allowed to remain unused for extended periods of time, these lead sulfate crystals grow in size and finally accumulate to the point where they form a physical barrier across the surface of the cell plates.
  3. The picture above depicts a battery plate that has accumulated a significant amount of sulfation.
  4. While the sulfation process will occur sooner or later, it can be hastened by a number of events such as, but not limited to, those described below:
  1. Shelf storage space was increased prior to installation. New batteries will soon get sulfated if they are left in storage or on a store shelf for any length of time. Sulfation occurs practically immediately after battery acid is introduced to a battery. A battery, regardless of how “fresh” it is, might actually fail within minutes of being fitted in a car. Leaving a car alone for a prolonged length of time
  2. Corrosion of the battery terminal, which increases resistance during the charge cycle, resulting in an undercharge condition
  3. Maintaining a state of discharge
  4. Temperature. For example, as the temperature of the surrounding environment rises, the rate of sulfation can double for every 10° increase in the temperature of the surrounding environment. If the outside temperature changes from 75° to 95°, sulfation can occur 400% more quickly than it would normally do so. The thickening of the vehicle’s fluids might be exacerbated by cold weather. This implies that it will need even more power to start the car, which means that the battery will have to discharge even farther, resulting in a quicker development of sulfates on the lead plates of the battery. Also bear in mind that if the battery is in an advanced state of discharge, the electrolyte might really freeze, which can cause damage to the lead plates and other components. Using a specific gravity of 1.270 (100 percent charged), it will freeze at -83° F
  5. Using a specific gravity of 1.200 (-17° F)
  6. And using a specific gravity of 1.140 (totally discharged), it will freeze at just 8° F. An undercharging condition occurs when the battery’s voltage is maintained at less than the maximum voltage, as occurs in cars that are used regularly and that stop and go repeatedly. In order to keep the car going at slower speeds or idling, the alternator must work harder to charge the battery at its maximum capacity. As a result, even when the car is running continuously throughout the day, the battery is not fully charged. And because it isn’t completely charged, it will begin to sulfate as soon as it gets warm. In this case, a vicious loop is generated, since the more that the battery sulfates, the less energy it will absorb, resulting in the battery being even more depleted of its charge. Eventually, it will perish as well

Sulfates have a detrimental influence on the performance of batteries:

  • Decreasing the ability of the battery to discharge electricity
  • Decreasing the ability of the battery to recharge
  • Batteries are losing their capacity faster than ever before – 80 percent of batteries globally fail prematurely.

Pulse Technology, a patented technology developed by PulseTech, is the most effective treatment for sulfation.

Prolong Batterys Lifespan Fighting Off Battery Sulfation

When you turn on your vehicle, golf cart, or industrial equipment with a battery in tow, you’re alert to the possibility that electricity will be an issue at some point. Most lead-acid batteries are used in heavy-duty applications throughout the industry. They are, on the other hand, to a certain extent dependable. Sulfation is an adversary of LA batteries that is concealed within their fundamental architecture.

Understanding sulfation will help you avoid the majority of the problems associated with a fading or completely dead battery. It is both exciting and frustrating to see the chemical reactions that occur within the battery at the same time.

The chemical environment

The majority of a conventional lead-acid battery is made up of sulfuric acid and lead compounds. While applying energy to the battery, the electrolytes in the liquid get agitated, which causes the battery to discharge. They are essentially the same thing. Having electrolytes that are continually moving and releasing electrons in a fully charged battery allows the power to be delivered gradually from the battery and into your vehicle or other equipment. According to Iota Engineering, sulfation can occur in any battery system.

Too much sulfation, on the other hand, causes power difficulties that are immediately noticeable by any user.

Your charging behavior

Everybody is guilty of failing to properly charge their batteries on a regular basis. You don’t have the luxury of taking your time to adhere to the “ideal” charge. According to Battery University, it takes between 14 and 16 hours to fully charge a lead-acid battery to its maximum capacity. The majority of individuals simply charge their batteries overnight, for a total of seven to eight hours. If a “perfect” charge is achieved with each session, sulfation does not occur on a widespread basis as a result.

As soon as the car is started, the battery continues to be charged throughout the journey.

Regularly taking short trips, on the other hand, causes sulfation, which shortens the battery’s life expectancy.

Symptoms of the “dying” battery

Because no one can charge a battery to exactly what it requires every time, the battery’s capacity will degrade at a steady pace over time. If you think about the indications that your battery produces when its life is about to expire, they include:

  • Less running times
  • Decreased power delivered to your load Charging periods that are too long in order to properly saturate the batteries

Because they are progressive, these symptoms tend to creep up on you without warning. The charging times are slowly diminishing, but they are quantitative in their decline. Take into account your charging habits as well as the battery’s age. It is possible that a replacement may be required in the near future.

Reviving the cells

With a continuous current applied to a fully charged battery, reversible or soft sulfation can be effectively corrected. The principle behind this activity is based on molecular excitation occurring at a high degree of intensity. During the passage of current through the battery, sulfate crystals that have formed on the plates and are inhibiting appropriate charging might dissolve and return to a state of liquid equilibrium. This action, on the other hand, does not work for every battery.

In fact, if you’re not using the right current, the activity can be quite harmful to you. When a battery is subjected to excessive power, it is possible for it to fail even worse. The best course of action when dealing with electricity concerns is to consult with specialists.

Heading into the future

Battery designers and sellers today are seeking for a straightforward solution to the problem of sulfation. The solution lies in a one-of-a-kind, acid-mixing battery. These unique batteries, known as ULTRAPOWER +Plus with MIXTECH, are constructed in such a way that the electrolytes are continually mixed throughout the charging and discharging process. Because the liquid is continually changing, it is impossible for excessive sulfation to develop on a large scale. When you’re done, you’ll have a battery that lasts twice as long as a conventional lead-acid battery.

Putting your trust in your local battery dealer is the most effective strategy to stay up with your power requirements.

We’re delighted to join you in the battle against sulfation as battery technology continues to develop and improve.
