Is your BMW having hard time starting?
Description
A BMW battery is a rechargeable battery that supplies electrical energy to your auto.It’s also called an SLI battery (abbreviation of starting-lighting-ignition) and its principal objective will be to start the BMW engine.
The alternator supplies electricity for the auto, once the engine is operating.
Normally, starting discharges less than three per cent of the battery capacity. SLI batteries are designed to release a high burst of current, measured in amperes, and then be quickly recharged.
They’re not designed for deep discharge, and a full discharge can decrease the battery’s lifespan.
