A typical car battery is enclosed in plastic and contains lead plates submerged in reservoirs of water and sulphuric acid, which allows for electricity to be conducted. The battery is used to power your car’s engine. It serves as a power source, supplying energy to the rest of the car’s electrical functions, such as the starter, lighting, heating, electric windows and sound system, among others. A battery also functions to stabilise and regulate power output to your vehicle, so energy is not wasted or dispersed unevenly.

If adequately maintained, a battery should last approximately 2 to 5 years.
