Having a hard time starting your GM?
Description
A GM battery is a rechargeable battery that supplies electrical energy to your auto.It is also known as an SLI battery (abbreviation of starting-lighting-ignition) and its chief purpose will be to start the GM engine.
Once the engine is running, the alternator supplies power for the auto.
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 are not designed for deep discharge, and also a complete discharge can decrease the lifespan of the battery.
