DescriptionA Audi battery is a rechargeable battery that provides electrical energy to your auto.
It’s also known as an SLI battery (abbreviation of starting-lighting-ignition) and its primary goal is to start the Audi engine.
Once the engine is running, the alternator supplies power for the car.
Commonly, starting discharges less than three per cent of the battery capacity. SLI batteries are made to release a high burst of current, measured in amperes, and then be quickly recharged.
They’re not designed for deep discharge, plus a full discharge can decrease the lifespan of the battery.
