Description
A Volkswagen battery is a rechargeable battery that provides electrical energy to your auto.It’s also called an SLI battery (abbreviation of starting-lighting-ignition) and its main purpose is to start the Volkswagen engine.
The alternator supplies power for the auto once the engine is running.
Normally, starting discharges less than three per cent of the battery capacity. SLI batteries are designed to discharge a high outburst of current, measured in amperes, and then be quickly recharged.
They’re not designed for deep discharge, along with a complete discharge can reduce the lifespan of the battery.
