Description
A GM battery is a rechargeable battery that provides electrical energy to your automobile.It’s also known as an SLI battery (abbreviation of starting-lighting-ignition) and its main objective is to start the GM engine.
The alternator supplies power for the GM, once the engine is running.
Generally, starting discharges less than three per cent of the battery capacity. SLI batteries are made to discharge a high outburst of current, measured in amperes, and then be immediately recharged.
They are not designed for deep discharge, along with the battery’s lifespan can be reduced by a complete discharge.
