The longevity of a car battery is influenced by its condition, usage, and upkeep. Consistent checks and care are essential for extending battery life. The actual duration varies based on personal usage habits.

“The abbreviation AGM stands for Absorbent Glass Mat.

AGM batteries are leak-proof and can also deal with inclined positions without problems. This, and their resistance to vibrations are the reasons why AGM batteries are especially favored for off-road and motorcycle use.

In comparison with conventional starter batteries, AGM batteries have a significantly longer cycle life.

Long life, excellent performance and greater safety make AGM batteries the premium batteries for modern vehicles.”

“EFB batteries (EFB stands for “Enhanced Flooded Battery”) are suitable for the power supply of cars with entry-level Start-Stop systems.

The design of EFB batteries is a further development of conventional flooded lead acid batteries.”

BEM stands for “Battery Energy Management”. Your vehicle’s control unit monitors it’s energy demand as well as taking values from coming the “Battery Management Sensor”(BMS) such as charge and energy throughput status of it’s battery into account. Today every modern vehicle with a Start-Stop function or a hybrid system holds a BEM.

Vehicles with advanced Energy Management Systems (such as those from BMW, Mercedes, and VAG) require a battery registration procedure using appropriate diagnostic tools after battery replacement.”

A lead-acid battery is a type of rechargeable battery that uses lead and lead dioxide plates immersed in sulfuric acid to store and release electrical energy.

Even with the advent of technologies like Li-Ion, lead-acid batteries continue to dominate the market for 12V batteries installed in passenger cars and commercial vehicles.

It’s important to understand that different lead-acid technologies are available, and proper functionality and long battery service life can only be guaranteed when the correct technology for your vehicle and usage profile is chosen.

Since the turn of the millennium, start-stop technology has been introduced in more and more vehicle segments and models to comply with increasingly stringent emission regulations. Nowadays, there are hardly any new vehicles that are delivered without a start-stop function. In other words, the newer the vehicle, the more likely it is to feature automated engine shutoff.

If the car is equipped with a Battery Management Sensor, it has a Start-Stop system or at least a Smart-Charging System that requires advanced battery technology such as AGM or EFB

For short journeys, proper recharging while driving of the battery is often a challenge. Here the consistent low internal resistance of an AGM battery throughout its lifespan offers a clear benefit.

This battery type features acid bound within a glass mat, preventing acid stratification and preserving the integrity of the active material. The consequent sustained charge acceptance is vital for maintaining a positive charge equilibrium and ensuring prolonged battery longevity.

“Similar to changing the oil, changing the tyres or servicing the air conditioning, the car battery must also be included in the maintenance routine and thoroughly tested.

Every time you take your vehicle to the workshop, you should have the battery checked.

It is important to analyze the state of the battery, before you suddenly have a breakdown at the worst possible moment.
Drivers should have their batteries checked by workshops at least once a year before winter.”

“For a car with a start-stop system, the recommended battery types are Absorbent Glass Mat (AGM) or an Enhanced Flooded Battery (EFB) battery.

If an AGM battery is already installed in the vehicle, it must always be replaced with another AGM battery since the vehicle’s Energy Management could overstress a Flooded battery which leads to shortend battery lifetime.”
