Car batteries of today are mostly maintenance-free with a performance indicator so there really aren’t many physical checks you can perform yourself. The only thing you need to do is make sure that the terminal connections are tightened without any debris. A neat trick is to coat the car battery terminal connections with petroleum jelly to further prevent the build-up of corrosive material. Remember to not tighten the battery terminals too much as it could damage the battery casing and lead posts and result in battery failure. Another important point to keep in mind is crossing the positive and negative terminals. This can cause an electric shock, permanent battery damage and even an explosion in some cases.
What does your battery do?
The purpose of a vehicle battery is to supply the necessary current to the starter motor and the ignition system while cranking to start the engine. In petrol engines, the car battery supplies power to the spark plugs to ignite the fuel and air mixture that has been compressed in the engine combustion cylinders. In addition, it also supplies extra current when the demand exceeds what the alternator can provide, and acts as an electrical storage unit. The battery power used when starting your car is then replaced by the alternator, which supplies most of the electrical current to your vehicle’s electrical systems. The strength of your car battery is generally affected by the amount of work it does and the operating conditions.
Why does a battery run out?
The modern technology in cars such as air conditioning, digital displays, music players, satellite navigation systems and other electronic gadgets place more strain on your battery. As a result, your car battery and charging system could lead to premature battery failure.
