Is your BMW having a hard time starting?
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 purpose would be to start the BMW engine.
The alternator supplies electricity for the auto, once the engine is operating.
Typically, 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 immediately recharged.
They are not designed for deep discharge, and the battery’s lifespan can be reduced by a full discharge.
