Charging during long idle periods
If the vehicle is stationary for long periods and you make a lot of short journeys, it is advisable to charge the battery regularly with a charger, even if the battery has a low self-discharge rate or high cold-start performance. The exact intervals depend …
The application determines how many volts are required.
In order not to damage either the connected loads or the battery, the voltage of the battery must fit.
Batteries are available with 6 or 12 volts. They consist of 3 or 6 cells of 2.12 volts each.
For applications that require more voltage, such as the …
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 …
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 …
The order of disconnection and connection
The negative terminal is connected to the body, hence the name grounding. If you accidentally touch the positive terminal and the body at the same time when the negative terminal is connected, e.g. with a metallic tool, a short circuit could occur that …
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 …
Whether short or long: charging takes place while driving
How much time does your battery normally have to charge? If your journeys are never shorter than 100 km, this is different from if you regularly only drive distances of 1 - 2 km. The alternator charges the battery with a steady, low current. It takes …
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 should you charge wet batteries open?
Gases are produced during charging. As they rise, they mix the battery acid.
It is better for the battery if it is open during this process.
Important: This only applies to initial charging and to all batteries that can be opened. Never open a battery by force!
Depending on the type, this battery is low-maintenance or maintenance-free.
Low maintenance version - TV types
Low-maintenance batteries can be recognised by the removable sealing plugs on the top, the vent hose and the white or transparent housing. In …
