The car battery starts the engine when you turn on the ignition. Once the engine is running, the alternator takes over to supply the car's electrical needs while restoring the charge to the battery. Prolong the life of your battery by getting into the habit of turning off all the lights, heated rear window and radio before you switch off the car engine.
To check the condition of your car battery, look for signs of cracks and other physical damage on the battery case and corrosion at the connections of large battery cables. A cracked battery needs to be changed immediately as the electrolyte leaking out is a mixture of sulphuric acid and water.
Top up the battery with distilled water whenever necessary to ensure that the acid level in each cell is above the plates. If you have a maintenance-free battery, you can skip the battery water, but you still have to check that the battery is secured and the terminals are corrosion-free.
