Description
A GM battery is a rechargeable battery that provides electrical energy to your automobile.It is also known as an SLI battery (abbreviation of starting-lighting-ignition) and its main purpose would be to start the GM engine.
The alternator supplies power for the GM, once the engine is running.
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 immediately recharged.
They’re not designed for deep discharge, along with a full discharge can decrease the battery’s lifespan.
