Stop by for a complimentary battery check at your local 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 Brougham’s battery post? If you notice white, crusty stuff around the battery terminals of your Brougham, 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 Brougham’s electrical system, potentially leading to poor performance, difficulty starting, and other issues.
  •  How do I clean corrosion off my Brougham vehicle battery? You can help prevent or get rid of corrosion by regularly inspecting and cleaning your battery terminals. Before cleaning your battery, see your Brougham 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.
