DescriptionA Car battery is a rechargeable battery that supplies electrical energy to your automobile.
It’s also called an SLI battery (abbreviation of starting-lighting-ignition) and its principal purpose would be to start the Car engine.
Once the engine is running, the alternator supplies electricity for the auto.
Typically, 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 immediately recharged.
They are not designed for deep discharge, and also the lifespan of the Car battery can be reduced by a full discharge.
