Is your BMW having hard time starting?
Description
A BMW battery is a rechargeable battery that provides electrical energy to your auto.It is also called an SLI battery (abbreviation of starting-lighting-ignition) and its chief objective is to start the BMW engine.
Once the engine is operating, the alternator supplies power for the BMW.
Usually, 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 quickly recharged.
They are not designed for deep discharge, and a complete discharge can decrease the battery’s lifespan.
