Is your BMW having difficulty starting?
Description
A BMW battery is a rechargeable battery that supplies electrical energy to your auto.It is also known as an SLI battery (abbreviation of starting-lighting-ignition) and its chief purpose will be to start the BMW engine.
The alternator supplies electricity for the BMW once the engine is running.
Generally, 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’re not designed for deep discharge, along with the battery’s lifespan can be reduced by a complete discharge.
