What does absolutely maintenance-free mean?
Absolutely maintenance-free batteries are valve-regulated lead-acid batteries or VRLA batteries (VRLA = Valve Regulated Lead-Acid) that are sealed at the factory. Here, significantly less gas is produced than in wet batteries. The gas produced remains …
A coherent equation: A lot out, a lot in.
Every battery loses power over time.
If it is loaded normally and is always fully charged, the capacity is slowly reduced.
If it is often overloaded and insufficiently charged, the capacity is reduced much more quickly, i.e. the battery ages much faster.
Ideally, …
Why does this battery have such a good current draw?
Due to the AGM technology, this battery absorbs the current particularly well, i.e. it recharges faster than a conventional wet battery and you can charge it with a higher charging current or a more powerful charger, like the ?
This characteristic comes …
What is wear and what can you do about it?
With a worn battery, the active material has degraded due to excessive load. Modern vehicles with many consumers constantly place higher demands on the battery. The capacity of the installed batteries is often not designed for this.
Prevention
The choice …
What does pole growth on the battery mean?
Whitish-grey deposits on the poles, so-called "pole growth", is caused by strong sulphation on the plates.
Tip: Always ensure a good state of charge.
What does damage to the battery box indicate?
Damaged battery box
If the housing is leaking, cracked or chafed, this indicates destruction by external influences.
Tip: Look for a robust design in your next battery.
Deformed battery case
If the housing is deformed by heat, this indicates a defective …
With each charge/discharge process (cycle), active material is inevitably lost and the battery's performance declines. Once it has fallen to the point where it can no longer fulfil its purpose - e.g. start the vehicle, supply the consumers or drive the …
Causal research for better purchasing decisions
Batteries age and fail. Sometimes it happens faster than you planned.
If you know the cause of premature aging, you have a chance to make a more appropriate choice now: A battery that fits your technical requirements, intended use, and individual habits …
Why are the labels coming off my battery?
Detached labels indicate wear due to excessive temperatures.
Tip: Always give your battery time to cool down before charging or use a charger that charges temperature compensated.
Tip: If you operate your vehicle or device in a very hot environment, choose …
Pay attention to the state of charge

Check the charge level every 2 - 3 months if ...
... the vehicle is often left unused.
... you drive a lot of short distances.
... many consumers are installed.
... it is cold.
... in start-stop systems the engine does not switch off as …
