Filling a dry pre-charged battery
Dry pre-charged batteries must be filled with battery acid and charged before installation.
Charging correctly step by step
Tip: For full performance: Charge before first installation!
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 low maintenance mean?
Low-maintenance batteries can be recognised by the removable sealing plugs on the top, the vent hose and the white or transparent housing. In these batteries, the electrolyte is in liquid form, i.e. it is not bound as GEL or in fleece. They are not sealed …
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 …
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. …
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 …
Check battery externally before charging
If the battery box is damaged or deformed, replace the battery.
Clean dirty terminals with a wire brush.
Remove oils, fluids or other deposits.
For batteries with plugs, check fluid level and refill to MAX with distilled water if necessary.
Always choose a battery that suits your individual requirements
Each battery technology has particular strengths, but also weaknesses. Depending on the requirements your battery has to meet in the respective application, or which properties you want, some battery technologies are more suitable or less suitable.
It is important to weigh up the properties.
Round cell drive batteries
The "wound" grid of the round cell battery combines the advantages of a supply battery with good starting characteristics in a relatively small space. The battery has good recharge behaviour after deep discharge and good cyclic behaviour (approx. …
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.
