Stop by for a complimentary battery check at your nearest Firestone Complete Auto Care and learn more about your battery's charge.

  • What is the average lifespan of a car battery? 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 substance accumulating on my M5’s battery post? If you notice white, crusty stuff around the battery terminals of your M5, 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 M5’s electrical system, potentially leading to poor performance, difficulty starting, and other issues.
  • How do I remove corrosion from my M5 car battery? You can help prevent or get rid of corrosion by regularly inspecting and cleaning your battery terminals. Before cleaning your battery, see your M5 owner's manual to learn how to disconnect the battery cables. After disconnecting the cables, use a mixture of water and baking soda, a wire brush, and a rag to carefully clean the terminals.
  • Where can I purchase M5 batteries near me? Your local Firestone Complete Auto Care sells and installs M5 batteries in your neighborhood. Our Firestone Direct mobile vans can even come to you and do it! Learn more about mobile battery services.
