Description
A GM battery is a rechargeable battery that provides electrical energy to your auto.It is also known as an SLI battery (abbreviation of starting-lighting-ignition) and its main purpose will be to start the GM engine.
Power for the car is provided by the alternator 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 outburst of current, measured in amperes, and then be quickly recharged.
They’re not designed for deep discharge, as well as a complete discharge can reduce the battery’s lifespan.
