Description
A Volkswagen battery is a rechargeable battery that supplies electrical energy to your auto.It is also known as an SLI battery (abbreviation of starting-lighting-ignition) and its chief purpose will be to start the Volkswagen engine.
The alternator supplies power for the Volkswagen, once the engine is operating.
Normally, starting discharges less than three per cent of the battery capacity. SLI batteries are designed to release a high outburst of current, measured in amperes, and then be immediately recharged.
They are not designed for deep discharge, along with the lifespan of the Volkswagen battery can be reduced by a full discharge.
