Is your BMW having hard time starting?
Description
A BMW battery is a rechargeable battery that supplies electrical energy to your automobile.It is also called an SLI battery (abbreviation of starting-lighting-ignition) and its primary objective is to start the BMW engine.
Power for the auto is provided by the alternator once the engine is running.
Typically, starting discharges less than three per cent of the battery capacity. SLI batteries are designed to discharge a high outburst of current, measured in amperes, and then be immediately recharged.
They are not designed for deep discharge, as well as the battery’s lifespan can be reduced by a total discharge.
