Your car battery is the heart of your vehicle’s electrical system. The battery stores and 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. If you're unsure of the age or lifespan of your battery, contact Dierks Diesel & Auto Performance in Deer Park at 509-262-8006 to schedule an appointment or click the 'Request Appointment' button above and schedule a visit online.
