Description
A GM battery is a rechargeable battery that provides electrical energy to your auto.It is also called an SLI battery (abbreviation of starting-lighting-ignition) and its primary goal is to start the GM engine.
Once the engine is operating, the alternator supplies electricity for the car.
Usually, starting discharges less than three per cent of the battery capacity. SLI batteries are designed to discharge a high burst of current, measured in amperes, and then be quickly recharged.
They are not designed for deep discharge, and the lifespan of the GM battery can be reduced by a full discharge.
