Your car battery is the heart of your vehicle's electrical system. Composed of a series of lead plates submerged in an electrolyte solution, your 12-volt car battery permits a chemical reaction to take place that produces electricity for use throughout the vehicle. The battery supplies electricity to all of the vehicle's electrical systems and components, including the power necessary to start and run your vehicle on a daily basis.
Batteries are very reliable, but they do have a limited lifespan. We recommend having your battery and charging system checked regularly and changed every 4 or 5 years as required. Be sure to ask your service advisor to check your battery's condition because when a battery fails today, there is generally no warning -- It just dies.
Failure to change your battery may also force your alternator to work harder leading to premature failure and costly replacement. From a safety standpoint, a dead battery won't likely pose a problem for other motorists but could leave you stranded on the side of the road. There is a low environmental impact unless there is a crack in the case as battery acid is hazardous and could be a threat to children, pets, and other animals.
