Description
A GM battery is a rechargeable battery that supplies electrical energy to your auto.It’s also known as an SLI battery (abbreviation of starting-lighting-ignition) and its principal purpose will be to start the GM engine.
The alternator supplies electricity for the auto once the engine is operating.
Commonly, starting discharges less than three per cent of the battery capacity. SLI batteries are made to release a high outburst of current, measured in amperes, and then be immediately recharged.
They’re not designed for deep discharge, as well as a full discharge can decrease the battery’s lifespan.
