DescriptionA Car battery is a rechargeable battery that provides electrical energy to your automobile.
It is also known as an SLI battery (abbreviation of starting-lighting-ignition) and its chief purpose will be to start the Car engine.
Once the engine is running, the alternator supplies power for the auto.
Generally, 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 are not designed for deep discharge, and the lifespan of the Car battery can be reduced by a full discharge.
