What are AGM, EFB and calcium batteries – and why would you need one?

What is the difference between an AGM battery and an EFB battery – and, more importantly, what is the difference between the two? What they are, how they function, and why you might need one are all explained here.

What is an AGM battery?

AGM is an abbreviation for Absorbed Glass Mat, which is a technical word. Because the electrolyte liquid (battery acid) is absorbed into the glass mats like a sponge, as opposed to being free floating as is the case with traditional batteries, an AGM battery differs from other types of batteries.

Why would I need an AGM battery?

Many of the technology and extras that are now standard in modern automobiles place additional strain on their batteries. AGM batteries are built to withstand the increased energy demands and discharges associated with these conditions. Because of the Stop-Start technology that is used in many current automobiles, a higher-capacity battery is required, and AGM batteries perform very well in this regard. To save gasoline, the car’s engine shuts off instead of idling while the vehicle is stationary when the Stop-Start feature is activated.

AGM deep cycle batteries are also safe to put within the cabin of a car to power accessories because they don’t emit toxic fumes when they’re being used.

If your vehicle is currently equipped with an AGM battery, it is critical that you replace it with another AGM battery in order to guarantee that the vehicle’s health is maintained.

AGMs have several advantages:

  • AGM batteries deliver greater amp power output for the same size of calcium battery, allowing them to keep up with the growing needs of automobile electrics and technology. AGMs are more suited to the contemporary automotive charging system than other types of batteries. Dual-purpose AGM batteries are capable of serving as both a starting battery and an accessory battery, allowing them to accommodate a wide range of innovative automobile accessories and technology. The use of deep-cycle AGMs in car passenger compartments is safer than the use of conventional AGMs since they are sealed and do not emit dangerous fumes or vapors. Due to the fact that an AGM is completely sealed, it requires no maintenance.

What is an EFB battery?

In addition, an improved flooded battery (EFB) can be utilized in vehicles that have Stop-Start technology installed. It is regarded as an entry-level battery for usage in automobiles equipped with this technology. EFBs are wet-filled batteries that are similar in appearance to ordinary flooded batteries; however, there are several changes that allow these batteries to have greater cycle abilities and charge acceptance. This implies that the battery recovers more rapidly, which is important because the battery’s application must withstand heavy-duty, cyclic, and Start-Stop applications.

Does my car need an EFB battery?

If your car already has an EFB battery, you will not be required to purchase another. Vehicles equipped with Stop-Start technology, for example, may make use of one of these batteries. If you are in any doubt, please contact us before obtaining a replacement battery. When a vehicle is equipped with Stop-Start technology, both AGM and EFB batteries are designed to withstand the frequent cycling that is necessary. New Stop-Start users may be concerned about the impact the feature will have on their vehicle’s battery.

However, the batteries that are necessary for this technology to operate properly are designed to withstand repeated stopping and starting. It is also the reason why it is critical to replace your battery with the proper type in order to retain its functionality.

What is a calcium battery?

Calcium batteries are lead acid batteries that have tiny quantities of calcium added to the plates to make them more resistant to acid corrosion. In most cases, battery plates are built of lead alloy; however, the mechanical strength of a pure lead grid structure is insufficient to hold the battery material vertically; thus, additional features must be added in order to boost the mechanical strength of lead. Antimony and calcium are the two alloyed metals that are most commonly utilized. The addition of antimony increases the electrical resistance of the alloys and, as a result, the electrical resistance of the grids made from them.

See also:  BFGoodrich tire discounts for tradespeople? (Professionals recommend)

Antimony-containing positive grids undergo conductivity, which implies that part of the antimony is liberated from the corrosive product of the grid and transported to a negatively charged negative plate.

Water loss is caused by this gassing phenomena in other batteries, resulting in the necessity to replenish water on a regular basis in order to keep the battery in good condition.

Does my car need a calcium battery?

The advantages of substituting antimony in the plates include enhanced corrosion resistance, the absence of excessive gassing, and the reduction in water use. The addition of calcium also helps to reduce the loss of charge that occurs as a result of the internal chemical processes that are necessary in the lead-antimony self-discharge procedure. As a result, they are less likely to be impacted by adverse weather conditions and higher charge rates than other types of vehicles. They are currently found in many modern automobiles, where they help to meet the increased power demands of engines and accessories.

  • Regardless of the advantages, calcium batteries should still be charged with a proper battery charger if they are not used on a regular basis.

Enhanced Flooded Batteries 101

The advantages of substituting antimony in the plates include enhanced corrosion resistance, the absence of excessive gassing, and the reduction in water use. Because calcium is used in the lead-antimony self-discharge, less charge is lost as a result of the internal chemical processes that occur throughout the process. As a result, they are less likely to be affected by harsh weather conditions and higher charge rates than other types of customers. Because of the increased power demand from engines and accessories, many modern automobiles now employ them to keep up with the rising demand.

However, even with the advantages, calcium batteries should still be recharged with a suitable battery charger if they are not used on a regular basis, regardless of their size.

  • There will be a significant increase in the number of starters. When the engine (and alternator) are turned off, the battery must provide electricity to the car. Charge acceptance is critical
  • The battery must be able to receive charge quickly in order to be able to complete a subsequent Start-Stop cycle. Regenerative braking capabilities, as well as a battery or super capacitor, should be used to store energy.

Batteries such as EFBs and AGMs were developed specifically to handle these start-and-stop applications. AGM batteries are frequently recommended, however their high cost has resulted in the more cost-effective choice of Enhanced Flooded Batteries becoming increasingly popular (EFB). The key advantages of EFB are as follows:

  • Charge uptake is improved as compared to the typical 12V flooding
  • The ability to operate at a decreased state of charge provides greater cycle endurance in comparison to typical 12V flooded. Technology that is less expensive than AGM technology

When compared to typical flooded batteries, the performance advantages of gel batteries are crucial in start-stop applications. According to studies, EFB batteries will yield 85,000 engine starts, compared to 30,000 engine starts from ordinary flooded batteries. What is the mechanism via which EFBs deliver these performance advantages? When comparing normal 12V flooded batteries to lithium-ion batteries, there are just two significant physical changes.

  • When active material is held in a narrow grid, the holding capacity of the active material is increased in order to prevent the active material from getting softened and falling, hence boosting charge uptake. Increased number of plates in the battery: this increases the response area of the battery, which improves charging performance.

Nonetheless, it is critical to recognize, given the way EFBs are designed and utilized, they are more prone to various sorts of failure if they are not maintained correctly. The combination of a smaller acid volume between plates and a greater number of charge/discharge cycles enhances the likelihood of stratification forming between plates. However, with EFBs, the story does not end there. As batteries drain, the concentration of acid in the battery reduces, resulting in an increase in lead ions.

  1. Because the plates in EFB batteries are designed so closely together, it is possible for the dendrites to join the plates and cause a short.
  2. The OCV and Specific gravity of standard flooded batteries are directly proportional to one another.
  3. Though the OCV is not charged properly, the OCV may grow even if the Specific Gravity does not increase in a corresponding amount as a result of the improper charging.
  4. Enhanced Flooded Batteries (EFB) can assist in the operation of many start-stop applications; however, due to the changes in performance, they have extra servicing needs than standard batteries.

As a result, deep cycle resistance and charge acceptance have been improved significantly. When the plates are bonded together, the plates maintain their appropriate position at all times and under all conditions.

Acid Circulation (Mixing Element)

The acid circulator prevents acid stratification from occurring. It is a structural device that makes advantage of the vehicle’s natural movement to maintain the acid inside the battery in continual circulation. It is important that the acid density remains homogeneous, since this improves charge acceptance and increases the total battery life.

What are EFB Batteries and how do they compare to AGM and ordinary lead acid?

Batteries that have been ‘Enhanced Flooded’ are referred to as ‘EFB Batteries.’ Flooded refers to being ‘wet’ or being filled with a solution of acid and water. Most automobile batteries are sold ‘wet’ charged, meaning they are ready to be used immediately after they are delivered to the customer. The battery acid in a dry cell battery, such as the one found in your phone or remote control, on the other hand, is not present. It makes use of the polar opposite in the form of an alkali, which is fine for usage around the house when compacted, powdered, or gel form, but not fine when not subjected to heat.

  • When a car battery is referred to as a ‘Enhanced Flooded Battery,’ it means that the internal structure of the ordinary lead acid battery has been enhanced.
  • While many contemporary automobiles utilize what is known as’start-stop’ technology to save gasoline while the vehicle is at a standstill in traffic, some employ a different method.
  • For example, the Fiat 500 Start-Stop version, the Toyota Yaris Start-Stop version, and the Ford ECOnetic range are all currently available vehicles that use the technology.
  • As long as the engine is turned off, no charge will be delivered to the battery.
  • AGM and EFB units can withstand the additional damage, but regular automobile batteries are unable to deplete to a particular charge level and efficiently bounce – back to full capacity.
  • Electricity is generated when the battery acid comes into touch with each lead plate, resulting from a chemical reaction.
  • After some time, the battery’s performance deteriorates and, in effect, ‘wears out.’ In addition to extending the life of the lead material, the polyfleecelining also serves to concentrate freshly converted electrons closer to each lead plate.
  • Additionally, the lead plates in both EFB and AGM batteries are physically thicker than those in conventional batteries.
  • What is the difference between EFB batteries and AGM batteries?
  • AGM batteries are spill-proof and have the ability to withstand high temperatures in the outdoors.

AGM vs Flooded Batteries – What You Need to Know

Rechargeable batteries are now used by the vast majority of businesses to power their cars, office equipment, and renewable energy systems. The lead-acid battery is the most widely used type of battery. This is an established technology that is regarded for being dependable, long-lasting, and cost-effective. However, there are many distinct types of lead-acid batteries to be aware of under the category of lead-acid batteries. Here, we shall discuss the distinctions between Absorbed Glass Mat (AGM) and Flooded batteries, which are both types of batteries.

When these batteries come into touch with a reverse current, they are re-charged.

What is a AGM Battery

Batteries with absorption glass mats, sometimes known as AGM batteries, were popular in the 1980s. They were once employed to power motorbikes, military vehicles, airplanes, and submarines, but they are now commonly found in regular automobiles and trucks. Alternative to standard flooded lead-acid batteries, AGM batteries have the advantage of requiring no maintenance. They are intended to generate high-intensity bursts of starting amps and to keep devices running for an extended amount of time.

How do AGM batteries work

An AGM (absorbed glass mat) battery is comprised of an unique glass mat separator that wicks the electrolyte solution between the batteryplate s. An AGM battery is also known as an AGM battery. In this material’s construction, electrolyte may be soaked into the fiberglass, which can then be stored in a ‘dry’ or suspended condition instead of being released into the surrounding environment as a free liquid. During the operation of the battery, electrolyte is moved from the glass mat to the battery plates as needed.

Pros and cons of AGM batteries

These batteries are referred to as ‘maintenance-free batteries’ since they do not require any type of maintenance. AGM batteries can operate better than flooded batteries in applications where maintenance is difficult to undertake since there is no loose liquid and low gassing.


Because they do not require watering, these batteries are referred to asmaintenance free batteries. As a result of the absence of free liquid and little gassing, AGM batteries can function better than flooded batteries in situations where maintenance is difficult to complete.

What is a Flooded Battery

Wet or flooded batteries, which are perhaps the most ‘traditional’ form of battery, are commonly employed in automobiles, stationary (big) continuous power sources, and, of course, stand-alone energy storage devices.

These batteries feature a mixture of liquid electrolyte and a solid electrolyte. In order for the battery to function effectively, the liquid level in these batteries must be carefully monitored and maintained at all times.

How do Flooded batteries work

To initiate a chemical reaction, flood batteries employ a liquid electrolyte-containing medium to discharge their charge. When the battery is connected, the acid in the battery forms a connection with the lead plates of the battery. This results in a chemical reaction that delivers an electric current across the circuit that is connected.

Pros and cons of Flooded batteries

When it comes to backup power applications, utility storage, and grid energy storage, wet cell batteries are often the best option. Additionally, as compared to AGM batteries, they are more cost-effective to operate.


The majority of the disadvantages of flooded batteries originate from the fact that they include free liquid, which necessitates periodic inspection and maintenance of the battery. Flooded batteries can potentially be harmed accidently when moving with a lot of force. Extreme weather conditions can have a bigger impact on battery life than normal weather conditions because the electrolyte solution inside the battery has the tendency to evaporate or freeze. In spite of the fact that flooded batteries require regular maintenance, they will survive far longer than many of their rivals if cared for correctly.

Enhanced vs Advanced and Robust Flooded Batteries: What Does It All Mean?

It has only been a few years since a variety of new terms and acronyms have been introduced into the automotive battery lexicon, including the terms Enhanced Flooded Battery (EFB), Advance Flooded Battery (AFB), and Robust Batteries. What makes them stand out from the competition, and what do they have to offer the consumer? Which one is genuinely offering new technology, and which ones are merely using different words to describe the same thing? The Battery Council International (BCI) recognizes three fundamental automotive battery technologies: the Flooded Battery, the EFB Battery, and the Absorbent Glass Mat (AGM) Battery.

The AGM battery differs from the other two in that the electrolyte has been immobilized in a non-spillable structure, making it non-spillable.

In accordance with the BCI definition, an EFB is ‘a flooded lead acid battery with improved cycle capabilities and charge recovery as compared to conventional flooded starting batteries.’ Furthermore, EFB batteries are developed to various standards, and they are made using different features and processes, so completely distinguishing themselves from the normal Flooded Battery group.

When it comes to battery technology, advanced and robust batteries are typically placed as the ‘Best’ in a Good/Better/Best battery line up.

These Advanced/Robust batteries are designed to meet or exceed the standard Starting, Lighting, and Ignition (SLI) criteria, which are defined by industry standards such as SAE J537, J2801, and/or EN50342-1, as well as other specifications.

A higher set of standards, defined by SAE J3012 and/or EN50342-6, are met by EFB batteries, which are designed to suit the needs of the end user.

While the SLI criteria do not include any requirements for partial state of charge cycling or dynamic charge acceptance, these two standards do include requirements for both.
