What does my battery do?
Without a charged battery - even the most powerful car is rendered immobile. Yet the battery is often one of the most neglected components in the entire car.
Here's how to make sure that you keep your car's battery in tip-top condition and avoid being stranded at the roadside without the power to get you going again.
The battery is most commonly located under the bonnet but in some cars it can be found elsewhere like under the floor in the boot. The two grey coloured posts on top of the battery are called 'terminals' and are marked ( + ) for positive and ( - ) for negative.
To avoid damaging the electrical system, the terminals should be connected to the appropriate electrical lead. If in doubt, consult your car's handbook or better still - leave it to the professionals at National.
Providing your car's alternator and drive belt are in good condition - the battery is re-charged automatically as you drive. In some cases, it can be removed from the car and connected to a domestic mains-powered battery charger - but care must be taken as the unit is heavy and contains sulphuric acid so it could be dangerous if dropped. If your car won't start a possible option is connect flat battery to another car's battery with jump leads ensuring that the leads are connected observing the correct polarity ( + ) and ( - ), however, ensure you refer to the manufacturer's handbook first. Some damage could result to the ECU in some cars if they are jump started, always check the manufacturer's handbook first.
Care and Maintenances
Most modern batteries require no periodic maintenance other than to keep the connections to the terminal clean and the fixing bolts tight. You can coat the terminals in petroleum jelly to prevent build up of corrosive material. In the event of the loss of any electrolyte in the cells, they can be topped up with distilled or demineralised water until the plates are covered..
Battery Check and Replacement
Eventually the internal condition of the battery deteriorates until it is unable to hold a charge and the battery has to be replaced. On a petrol engine car the first symptom of this is usually that it feels sluggish when you start the car. On a diesel engine car, it will usually just fail to start due to the higher cranking power needed for diesel.
In-car entertainment and other electrical devices put your battery under even more strain meaning that it's now more important than ever to have your battery checked. Every day around 1,000 vehicles break down due to battery failure and faulty batteries are one of the main reasons for breakdown calls.
Your local National technician can carry out a FREE battery check which only takes a few minutes and will advise you on exactly the right type of battery for your car depending on the engine size and the typical conditions in which you use your car.
