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 chief objective will be to start the GM engine.
Once the engine is running, the alternator supplies electricity for the GM.
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 the lifespan of the GM battery can be reduced by a complete discharge.
