  •  How long do car batteries 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.
  • What is the white, crusty stuff around my 540i’s battery post? The white, crusty stuff that can accumulate around 540i car battery terminals is called corrosion. It is caused by a chemical reaction between the battery acid and the air, which creates a white, powdery substance that can build up on the terminals over time. Corrosion can interfere with the flow of electricity between the battery post and the car's electrical system, sometimes leading to poor electrical performance, difficulty starting, and even premature battery failure.
  • How do I clean a corroded 540i 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. Always reference and follow the instructions in your vehicle owner’s manual prior to disconnecting the battery cables.
