First of all, a battery must fit in your vehicle or machine. Check the dimensions of your old battery or the available space in the battery compartment of your vehicle.
The placement of the terminals, i.e. where exactly the positive and negative terminals …
Determine excessive self-discharge
If the battery charge drops significantly, possibly overnight, this may be due to leakage current. Silent, unwanted loads can be detected with an ammeter. Oils or liquids deposited on the surface of the battery can also cause considerable self-discharge. …
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 …

The choice …
Charging correctly step by step
Tip: For full performance: Charge before first installation!
1. preparation
Check that your charger matches the battery.
Does the charger support the correct charging voltage?
Does the charging current provided match the battery?
What charging curve …
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 …
Identifying and filling the liquid level
Markings on the outside of the white or transparent housing of a wet battery indicate the minimum (MIN) and maximum (MAX) fill levels.
During commissioning or initial filling, the battery must be filled with battery acid up to the upper mark (MAX).
During …
Why are the labels coming off my battery?
