Is your BMW having hard time starting?
Description
A BMW battery is a rechargeable battery that supplies electrical energy to your automobile.It is also known as an SLI battery (abbreviation of starting-lighting-ignition) and its principal purpose will be to start the BMW engine.
The alternator supplies power for the auto once the engine is operating.
Usually, 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 quickly recharged.
They are not designed for deep discharge, as well as a complete discharge can decrease the battery’s lifespan.
