Stop by for a complimentary battery check at your favorite Firestone Complete Auto Care to learn more about the state of your battery.

  • How long can I expect my car battery to last? You can usually get three to five years out of your car battery. However, battery type, how well you maintain your battery, and your driving habits can all affect your battery’s lifespan.
  • What is the white, crusty stuff around my Cutlass Supreme’s battery post? A chemical reaction between battery acid and the air can cause a white, crusty buildup to form on the terminals of your Cutlass Supreme car battery. This buildup — known as corrosion — can impede the flow of electricity and cause a range of issues, from poor performance to premature battery failure.
  • How do I clean a corroded Cutlass Supreme battery terminal? Regularly inspect the terminals and clean them with a mixture of baking soda and water, a wire brush, and a rag. Disconnect the battery cables before cleaning to help avoid the risk of electrical shock.
