Description
A GM 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 primary goal would be to start the GM engine.
The alternator supplies power for the GM once the engine is operating.
Commonly, 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 immediately recharged.
They are not designed for deep discharge, as well as a complete discharge can reduce the battery’s lifespan.
