To ensure proper battery function, it makes sense to keep the battery surface clean and dry. Greasy or silicone-containing dirt on the lid can hinder the flow of current. Moisture on the battery can cause a short circuit in the worst case.
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 …
Checking the liquid level against sulphation
In a battery or accumulator, the chemical reaction between the active material of the grids and the acid generates current (electrons emitted) to supply the loads or stores current (electrons) provided by the charger or alternator.
If the acid only partially …
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 …
Always choose a battery that matches the load
Depending on the type of battery, it is designed for certain loads:
Starter batteries must deliver as much current as possible during the starting process. The cold start current, measured in CCA, is informative here and shows how much starting power …
What is a back-up battery?
In some cars, so many consumers are installed from the outset that it would overload the starter battery to supply them. This is where so-called back-up batteries are used.
If your car is equipped with a back-up battery, you should replace it again with …
What do deposits on the battery plugs mean?
Black deposits on the plugs indicate a battery that has worn out prematurely due to continuous excessive load.
Tip: Always ensure a good balance between current drain and charging.
Information on capacity calculations and charging behaviour can be found …
For normal passenger cars, also US vehicles, Asian models and classic cars, mostly modern, maintenance-free flooded batteries are used, such as the intAct Start-Power NG, the intAct Race-Power or the intAct Premium-Power.
These batteries are suitable …
What the cold start performance says
Starter batteries primarily have to start the vehicle. To do this, they must deliver as much current as possible during the starting process, so the battery's high-current characteristics are important. The cold cranking amps (CCA) value provides information …
Filling a dry pre-charged battery
Dry pre-charged batteries must be filled with battery acid and charged before installation.
