Absorbent Glass Mat (AGM) Lead-Acid Advanced Technology
Upgrade to AGM to get the best of the best. By choosing an AGM battery with the most advanced technology, you will get an outstanding battery that is capable of powering the most demanding vehicles and accessories. The innovative VARTA® AGM technology offers three times the endurance of conventional batteries, perfect for advanced start-stop systems in which the battery needs to be quickly recharged through the energy provided by the regenerative braking system.
Our Powersports AGM battery is designed with extreme conditions in mind. With the (AGM) lead-acid built in, this sophisticated product provides maximum power over a long life and is completely maintenance-free.
Absorbent Glass Mat (AGM)
The special AGM lead-acid soaks up all the acid in the battery, providing high cyclic stability. This enables the battery to be repeatedly charged and discharged without any loss of performance.

VARTA® AGM advanced technology for start-stop cars
The Basic Principles of Start-Stop Technology
Start-stop systems automatically shut down and restart the engine to reduce the amount of time it’s idling, therefore cutting down on fuel consumption and emissions. The majority of manufacturers choose to fit VARTA® batteries in their start-stop vehicles rolling off the production line.
The battery is at the heart of the car. It powers everything – from the ignition to continuously operating vehicle electric systems and onboard entertainment systems. The battery ensures constant power for all other functionalties during the start-stop process. Those batteries have to do much more than just starting the car. That’s why the BATTERY is the HEART of your vehicle.
Today most new cars have start-stop functionalty, which is why we have created two innovative VARTA® batteries with start-stop capability: VARTA® Silver dynamic with AGM technology for advanced start-stop vehicles with regenerative braking, and Blue dynamic with EFB technology for conventional start-stop vehicles.

Driving & Accelerating
An advanced energy management system decouples the alternator during acceleration and under normal driving conditions. This means more of the engine’s power is available to the wheels. The alternator is only recoupled again when the battery’s state of charge falls below a predefined threshold.
Battery requirements:
Battery is being discharged and charged and must supply all electronic devices on its own.
Video Player
Braking
Regenerative braking partially allows the vehicle’s kinetic energy to be converted into electrical energy, which is then fed back into the battery.
Battery requirements:
The battery needs to be recharged quickly and have sufficient capacity for the additional energy. The battery must be capable of functioning at a lower state of charge.

Stop & Engine Off
When the vehicle comes to a stop, the start-stop system switches off the engine.
Battery requirements:
Even when discharged, the battery must still supply the starter motor generator with sufficient starting power to start the engine again.
EFB Enhanced Technology
VARTA® offers enhanced flooded battery (EFB) products that deliver superior reliability and performance compared to standard lead-acid batteries for automotive and commercial vehicle applications. Our batteries are built to meet customers’ individual needs and are manufactured in facilities throughout Europe to meet the highest quality standards.
EFB Technology for Cars
EFB batteries support applications that operate at a partial state of charge and don’t require the deep-cycling characteristics of an AGM battery. A polyfleece scrim material, added to the positive plate surface, makes this possible. This helps to stabilise the active material of the plates, which increases the endurance.
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.
- Designs available that improve thermal stability for use in engine compartments and hot climates.
- Ideal for start-stop vehicle technologies without regenerative braking technology and for vehicles with higher-than-normal energy demands, whether that means a tougher drive schedule or multiple accessories and equipment installed.
- In addition, our EFB products are built with PowerFrame® grid technology for high starting power and reliable performance.
EFB Technology for Commercial Vehicles
The unique VARTA® Promotive EFB is a specifically designed battery for high-performance commercial vehicles and is the state of the art in acid stratification and vibration resistance. It is the only product in the market with mixing elements, exclusively developed and patented by Clarios, formerly Johnson Controls Power Solutions. EFB technology ensures reliable performance for all highly demanding applications and is ideal for end-of-frame installation.
Benefits include:
- A unique mixing element inside reduces acid stratification and is an optimum solution for all deep discharge applications. It’s a mechanical system that uses vehicle inertial forces to aid the mixing of acid in flooded batteries.
- Superior internal fixations with best-in-class hot melt: Very high vibration resistance and perfect fit for end-of-frame installation ensure highest product performance.
- The unique Labyrinth Lid design provides 100% spill protection and very low water consumption.
- High cycling ability is guaranteed by using PowerFrame® technology, improved positive paste and grid-to-mass adhesion. A polyfleece scrim material, added to the positive plate surface, sustainably improves cycle life performance.
- Minimizes warranty cost.
EFB Technology Features
Scrim is an additional polyester element between plate and separator. The scrim holds the active material in place inside the plate and avoids the erosion of mass. 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.
Acid Circulation (Mixing Element)
The acid circulator avoids acid stratification. It’s a construction element that uses the natural movement of the vehicle to keep the acid inside the battery in constant circulation. The acid density stays at homogenous levels, which enhances charge acceptance and extends the overall battery life.

THE ROLE OF THE BATTERY
FACTORS THAT AFFECT BATTERY LIFE
-
Extreme Temperatures
Excessive heat can cause sulfation and corrosion inside your battery. You usually notice the problem (trouble with cold starts and poor charge acceptance) during cold weather.
-
Irregular Use
A parked car uses up to 1% of the battery´s charge for standby functionality. In addition depending on the ambient temperature and the age of the battery, self-discharge can drain the battery within a few weeks.
-
Short Trips
Driving only short distances does not give your battery enough time to recharge. In winter, high-consumption accessories such as defrosters and heated seats make matters worse.
-
Older Vehicles
As your car ages, the performance of its battery declines due to corrosion and sulfation. The sulfate crystals that form can clog the pores of your battery’s plates, preventing proper charging.
