Almost every car in existence today uses a battery for its electrical systems, primarily the starting, lighting and ignition but also for the air conditioning, heaters, radio and everything else. It powers the starter motor and ignition by providing the electrical source they need. Car batteries are usually an acid type battery, with six cells in a series to provide the required 12 volts. They work as the acid causes a chemical reaction that releases electrons, which in turn flow through the conductors as electricity.
Most vehicles incorporate an alternator so the battery retains charge while the ignition is on, so that the battery doesn’t run flat while the car is running. However, while the ignition is off the battery drains, which is why cars can fail to start when left with the lights or radio on for too long.
If your battery runs flat there are a number of ways to get your car to start again, either by recharging the battery or in an emergency the car can be jump-started. However if you find your battery keeps on losing its charge, and it isn't due to negligence on your part by leaving the electrics on while the car is not running, then there could be a fault either with the battery or alternator.
