A car battery is an electrical storage device. Batteries don’t make electricity they simply store the power until you are ready to use it. So when you turn the key to start your vehicle, the battery supplies power to the starter motor, which turns the engine over. At the same time, power from the battery is supplied to the spark plugs in order to ignite the fuel and air mixture in the engine combustion cylinders. The battery power used during the start up process is then replaced by the alternator, which supplies most of electrical current to your car's electrical systems, keeping your battery fully charged.

The battery strength (ampage) is generally affected by the amount of work it needs to do and the conditions in which it has to work in. Also, over the years, in-car technology has grown to include items such as air conditioning, iPods, sat nav systems and other electronic gadgets. All of these increase the demand on the car’s battery and charging system. Consequently more frequent checks are recommended so that your car battery maintains its optimum working level.
Regular battery checks can help identify and prevent premature ‘battery failure’, which can result in a vehicle breakdown at a most inconvenient time.
