Description
A GM battery is a rechargeable battery that provides electrical energy to your automobile.It is also called an SLI battery (abbreviation of starting-lighting-ignition) and its principal purpose would be to start the GM engine.
Once the GM engine is running, electricity for the auto is supplied by the alternator.
Usually, starting discharges less than three per cent of the battery capacity. SLI batteries are designed to release a high outburst of current, measured in amperes, and then be quickly recharged.
They’re not designed for deep discharge, plus a complete discharge can decrease the lifespan of the battery.
