Description
A BMW battery is a rechargeable battery that provides electrical energy to your automobile.It’s also known as an SLI battery (abbreviation of starting-lighting-ignition) and its primary purpose will be to start the BMW engine.
Once the BMW engine is running, power for the car is provided by the alternator.
Commonly, starting discharges less than three per cent of the battery capacity. SLI batteries are made to discharge a high burst of current, measured in amperes, and then be quickly recharged.
They’re not designed for deep discharge, plus the lifespan of the BMW battery can be reduced by a complete discharge.
