Is your BMW having 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 main purpose is to start the BMW engine.
The alternator supplies electricity for the auto once the engine is running.
Generally, 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, along with the lifespan of the BMW battery can be reduced by a full discharge.
