Your guide to battery maintenance
70% of batteries don’t even make it four years. Eventually your car battery will fail and you will need to replace it. There are some things car owners can do, however, to make their battery last a little longer. It’s all about the flow of electrical power. When you start your vehicle, the battery uses power to get your engine cranking. As your engine runs, your alternator generates electricity to run all your electrical systems: like lights, a half dozen computers, anti-lock brake system, traction control, power windows, electronic fuel injectors, stability control, air conditioning, transmission servos – the list goes on.
