Having a hard time starting your BMW?
Description
A BMW battery is a rechargeable battery that supplies electrical energy to your auto.It is also called an SLI battery (abbreviation of starting-lighting-ignition) and its chief goal will be to start the BMW engine.
Power for the auto is supplied by the alternator once the engine is operating.
Commonly, starting discharges less than three per cent of the battery capacity. SLI batteries are designed to discharge a high burst of current, measured in amperes, and then be quickly recharged.
They are not designed for deep discharge, along with a complete discharge can decrease the lifespan of the battery.
