The purpose of your vehicles battery is to supply the necessary current to the starter motor and the ignition system while cranking to start the engine. It also supplies additional current when the demand is higher than the alternator can supply and acts as an electrical reservoir.
A number of systems in your car depend on your battery - radio, built-in GPS, USB port, phone chargers etc.
