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 chief goal will be to start the BMW engine.
Once the engine is operating, the alternator supplies electricity for the BMW.
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 immediately recharged.
They are not designed for deep discharge, and also a complete discharge can decrease the lifespan of the battery.
