Description
A GM battery is a rechargeable battery that supplies electrical energy to your automobile.It is also called an SLI battery (abbreviation of starting-lighting-ignition) and its primary objective is to start the GM engine.
Once the engine is operating, the alternator supplies electricity for the car.
Normally, starting discharges less than three per cent of the battery capacity. SLI batteries are made to release a high burst of current, measured in amperes, and then be immediately recharged.
They’re not designed for deep discharge, as well as a complete discharge can reduce the battery’s lifespan.
