By the BCI definition, an EFB is “a flooded lead acid battery with enhanced cycling capability and charge recovery compared to standard flooded starter batteries.” Taking this a step further, EFB batteries are designed to different standards and manufactured with different attributes and techniques to fully
- Enhanced flooded battery — EFM battery definition EFB battery An enhanced flooded battery (EFB battery) is an enhanced version of the traditional flooded lead-acid battery. It’s used in vehicles with stop/start functionality to improve starting and standby power and to accommodate regenerative braking recharging.
What does EFB on a battery mean?
An enhanced flooded battery (EFB) can also be used in cars that feature Stop-Start technology. It is considered an entry level battery for use in cars with this technology. This means the battery recovers more quickly, as its application needs to handle heavy-duty, cyclic, Start-Stop applications.
What’s the difference between EFB and AGM battery?
What are the differences between EFB and AGM batteries? A. EFB batteries have been introduced as a lower tier option to AGM batteries in terms of performance and durability. EFB technology relies on improvements to existing flooded technology through the addition of Carbon additives in the plate manufacturing process.
What kind of battery is EFB?
EFB Batteries are ‘ Enhanced Flooded Batteries’. Flooded means ‘wet’ / filled with a mixture of acid and water. The vast majority of motor vehicle batteries when sold, are ‘wet’ charged and ready to use straight away.
Is a EFB battery a deep cycle battery?
EFB Technology Features The result: enhanced deep cycle resistance and superior charge acceptance. The glued fleece helps the plates keep their proper position at all times and in every condition.
What is the advantage of EFB enhanced flooded battery batteries of conventional batteries?
Benefits include: More than twice the partial state of charge and deep-cycling performance of conventional batteries. Support for a high number of engine starts and extended engine-off periods. Improved charge acceptance compared to conventional flooded batteries.
Are EFB batteries any good?
EFB batteries have a low internal resistance and are characterized by twice the number of charging cycles* in comparison with conventional starter batteries, as well as a high load capacity. EFB batteries are suitable for the power supply of cars: with simple automatic start-stop systems.
Can I replace EFB battery with AGM?
With an EFB battery you have two options: Either replace it with another EFB or install an AGM. The latter can increase the efficiency of the automatic Start-Stop system and result in a more efficient fuel consumption.
Can I use AGM battery instead of EFB battery?
In addition, when replacing the battery, it is possible to replace the AGM with EFB, but it is not possible to replace the EFB with AGM, because AGM cannot be used in high temperature environment.
How do you charge an EFB battery?
How to recharge a car battery
- Check what kind of battery your vehicle has. If your car has start/stop technology, you’ll have an AGM or EFB battery.
- Check the contacts.
- Disconnect your car battery.
- Connect the charger.
- Turn on the charger.
- You’re done!
What is a flooded battery?
Flooded or ‘ wet cell’ batteries are the most commonly used batteries on the market today. Flooded batteries again use lead plates, a sulfuric acid electrolyte, and plate separators but that is where it stops. Usually flooded batteries are not sealed, and do not recombine the gases to liquids internally.
Do I need a special charger for EFB battery?
EFB batteries are an enhanced version of standard wet-flooded technology. These types of batteries should not be confused with standard flooded or AGM batteries. EFB’s can be charged using standard modern intelligent chargers ( no specific charging pattern, unlike AGM batteries).
How long do EFB batteries last?
The EFB battery is for simpler stop/start electric systems with smaller engines. This battery can live from 3 to 6 years.
Are EFB batteries lead acid?
Manufacturers define EFB batteries as vented (flooded) lead–acid starter batteries, with additional design features to improve significantly the starting performance, cycling capability and service-life compared with standard flooded batteries, especially for start‒stop vehicle applications.
Do EFB batteries need venting?
Yes you do need to vent it, you need a piece of plastic tube, I think 6mm bore from memory, you may need a spout to go in the battery vent if it doesn’t come with one, then through the rubber bung that’s already in the floor under the passenger seat to outside.

Enhanced flooded battery — EFM battery definition
EFB batteries, also known as enhanced lead-acid batteries, are an improved version of the standard flooded lead-acid battery. Vehicles equipped with stop/start functionality benefit from the addition of this component, which improves starting and standby power as well as providing space for regenerative brake recharge.
EFB battery advantages over flooded lead-acid battery
Enhanced flooded batteries are intended to help you save money on your electric bill. They outperform a typical flooded lead-acid battery, although not as well as an AGMbattery in terms of performance. If your car was originally equipped with an EFB battery, you must replace it with another EFB battery in order to keep your vehicle running. A normal flooded lead-acid battery installed in a stop/start car will have a significantly reduced battery life – as little as six months! Rick Muscoplat posted a blog entry on
AGM & EFB Automotive Batteries Explained
- Because to improved acid absorption, the active mass efficiency has been increased. Battery design has resulted in reduced active material loss, which has resulted in increased battery longevity. Cold start values that are higher
- The system is completely maintenance-free and uses no water. Spill- and leak-proof construction
- Designed to fulfill the most recent OEM vehicle requirements
- Compatible with electronic equipment that is sensitive
- In addition to several premium automobiles and ‘stop-start’ vehicles, when enhanced AGM battery characteristics are necessary, AGM technology is now factory installed in a variety of other vehicles.
Yuasa’s AGM (absorbent glass mat) technology, which is already a world leader in motorcycle and industrial applications, is now available in the automobile sector. The Yuasa automotive AGM battery has been designed to handle the increasing severe power needs of recently launched automobiles that are now beginning to reach the European aftermarket. Yuasa automotive AGM batteries are available in a variety of capacities. Automotive AGM knowledge from Yuasa originates from cars such as the Mazda MX5 and the well-known Toyota Prius, and it has now been extended to vehicle battery designs for use in the European market.
Testing in the laboratory has revealed that the product has four to five times the cycle durability of normal traditional flooded product, as well as approximately sixteen percent more starting power, even at lower temperatures.
The absorbent glass mat technology utilized in the AGM batteries is the same as that used in Yuasa Motorcycle and Industrial batteries, which have been on the market for over 44 years and are still going strong (1965).
The use of an absorbent glass mat in the construction of a lead acid battery provides a number of important advantages, including the following:
- Under typical operating circumstances, the employment of the individual cell valve design and glass mat plate separation assures that gas recombination occurs and that no water is wasted, hence eliminating the need for electrolyte reservoirs and relieving the user of the burden of maintaining the system. One-way venting system that creates partial pressure in each cell, guaranteeing that the cell is completely leak proof and safe to handle
- Because of the acid absorption of the glass mat, the battery packs can be operated at higher pressures than conventional flooded batteries. This has several advantages, including significantly increasing battery cycle durability by reducing paste shedding
- And significantly extending battery cycle durability by reducing paste shedding. Vibration resistance of the AGM battery is improved as a result of the increased pack pressures. A greater amount of response surface area ensures greater starting capacity while maintaining the same footprint as conventional?flooded batteries.
Frequently Asked Questions
In terms of lead acid batteries, what are the distinctions between flooded and AGM lead acid batteries? a. As previously stated, AGM batteries are constructed with a glass mat separator, which allows all of the electrolyte required by the battery to be stored within the glass mat, while also permitting any gases emitted by the battery during charging to be recombined into water, resulting in a battery that requires no maintenance at all. The design advantages of AGM batteries over conventional flooded batteries allow the battery pack to operate under higher pressure without the worry of insufficient electrolyte between the plates, resulting in the significant increase in durability offered by AGM batteries over conventional flooded batteries over time.
- With over 44 years of experience in the industry, Yuasa has developed valuable knowledge and expertise in employing this technology.
- QUESTION: What are the distinctions between GEL and AGM (starved) batteries?
- Most notable is that in AGM batteries, the electrolyte is completely absorbed into a special absorbed glass mat separator, which immobilizes the acid, whereas in GEL batteries, the acid is mixed with Silica to form a GEL that also immobilizes the acid.
- In comparison to gel batteries, the use of absorbed glass mat allows the battery pack to be run at a higher operating pressure, which increases the cycle endurance of the battery pack over time.
- This implies that the oxygen that is ordinarily created on the positive plate of all lead acid batteries interacts with the hydrogen that is released by the negative plate of the battery.
The sealing vent employed in the design guarantees that a positive internal pressure is maintained, allowing for the recombination of the gasses to take place while preventing the cell from drying up and failing.?
(for example, due to an alternator rectifier malfunction), or the cell will be permanently destroyed.
It should be noted that after an AGM battery has been sent from the factory, it should never be opened again since sulphation on the plates might occur, resulting in an irreversible loss of performance.
AGM batteries, on the other hand, are not vulnerable to this failure mode and are therefore more appropriate for automotive applications.
In the case of flooded batteries, provided that the batteries are not damaged, A.
What is the best way to store an AGM battery on the garage floor?
In the olden days of hardwood/glass case batteries, when moist flooring caused water to leak into the outer wooden cases, resulting in swelling of the wood, this myth was perpetuated by the media.
The most important consideration is that there should be no sharp items on the floor that might harm the battery shell; there are no electrochemical reasons for this.
Q. Do AGM batteries retain their charge after being discharged? A. No, this is exclusively a function of Nickel Alkaline Battery systems, such as nickel cadmium, and not of other types of batteries.
Also known as AFB (Advanced Flooded Battery) and ECM (Electrical Control Module) (Enhanced-Cycling-Mat)
Yuasa EFB (Enhanced Flooded Battery)
- Developed to fulfill the most recent OEM vehicle requirements
- EFB technology is currently standard equipment on a large number of entry-level Start-Stop automobiles. In comparison to typical wet-flooded batteries, improved design features such as specific Carbon additives and high charge acceptance envelope type separators have resulted in an increase of 170 percent in dynamic charge current acceptance. In comparison to normal wet-flooded batteries, the cycle durability has been increased by 100 percent. Double-sealed tip-and-tilt lid with integrated flame-retardant system

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.
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.
- 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.
- The OCV and Specific gravity of standard flooded batteries are directly proportional to one another.
- 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.
- 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.

EFB Technology Features
Scrim is a polyester piece that is placed between the plate and the separator. The scrim keeps the active material in place inside the plate and prevents the plate from becoming eroded in the process. 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.
