Description
A BMW battery is a rechargeable battery that provides electrical energy to your automobile.It is also known as an SLI battery (abbreviation of starting-lighting-ignition) and its principal objective will be to start the BMW engine.
Electricity for the car is supplied by the alternator once the engine is running.
Usually, starting discharges less than three per cent of the battery capacity. SLI batteries are made to discharge a high outburst of current, measured in amperes, and then be quickly recharged.
They’re not designed for deep discharge, and a total discharge can reduce the lifespan of the battery.
