  • Why won't my S battery stay charged? A battery that won't hold a charge is almost as good as dead. It may be getting old. Or, you may have a habit of leaving your car doors open and the cabin light at night. Stop by for a complimentary battery check at your nearest Firestone Complete Auto Care and get a handle on your car battery’s health.

  • How long can I expect my car battery to last? A car battery normally lasts three to five years, but this number can vary based on battery type, your driving habits, and battery maintenance.
  • Why is there white, crusty buildup on my S’s battery post? If you notice white, crusty stuff around the battery terminals of your S, it's likely corrosion. A chemical reaction between battery acid and the air can create a white, powdery substance that builds up over time on the terminals. This buildup can interfere with the electrical connection between the battery and your S’s electrical system, potentially leading to poor performance, difficulty starting, and other issues.
  •  How do I clean corrosion off my S vehicle battery? 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. Always reference and follow the instructions in your vehicle owner’s manual prior to disconnecting the battery cables.
