Your car battery is the heart of your car's engine.

Without a charged battery, your car is rendered immobile. Modern cars rely more and more on the battery for the operation of anti-theft devices, heating, electrically operated windows, in-car entertainment, the list goes on. Yet the battery is often one of the most neglected components in the entire car. Although today's car batteries are generally sealed units and do not require topping up (see your vehicle handbook for more details), there are some things you can do to ensure trouble free battery operation.

Battery Connection

The battery is most commonly located under the bonnet. The two grey coloured posts on top of the battery are called the "Terminals". Should the terminals become corroded, this may impair the electrical contact. The terminals can be kept corrosion free by applying a light film of petroleum jelly. To avoid damaging the vehicles electrical system it is imperative that the terminals are connected to the appropriate electrical lead. If in doubt, consult your car's handbook or, better still, drop into us.


The alternator and drive belts keep your battery charged as you drive. Should the battery become discharged, it should be removed from the vehicle and connected to a mains-powered charger. Your vehicle's charging system is not designed to recharge a dis-charged battery, merely to top up a fully powered battery.

Very often it’s only during the cold winter mornings when our battery lets us down. A battery which is under charged or nearing the end of its life will discharge quicker in lower winter over-night temperatures.
