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