  • How often should I replace my car battery? A car battery normally lasts three to five years, but this number can vary based on battery type, your driving habits, and battery maintenance.
  • What is the white, crusty stuff around my Boxster’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 Boxster 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.
  • What do I do about corrosion on my Boxster car 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.
