Is your BMW having difficulty starting?
Description
A BMW battery is a rechargeable battery that provides electrical energy to your auto.It is also known as an SLI battery (abbreviation of starting-lighting-ignition) and its chief goal will be to start the BMW engine.
Once the engine is running, the alternator supplies electricity for the auto.
Usually, starting discharges less than three per cent of the battery capacity. SLI batteries are made to discharge a high outburst of current, measured in amperes, and then be quickly recharged.
They are not designed for deep discharge, and also a full discharge can decrease the battery’s lifespan.
