  • How long is a car battery good for? 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 545i’s battery post? If you notice white, crusty stuff around the battery terminals of your 545i, 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 545i’s electrical system, potentially leading to poor performance, difficulty starting, and other issues.
  • What do I do about corrosion on my 545i car battery? Regularly inspecting and cleaning your battery terminals will help keep your 545i’s electrical system running smoothly. Before cleaning, reference your owner’s manual for instructions on how to disconnect the battery cables. Once the cables have been disconnected, gently clean the terminals with a mixture of water and baking soda, a wire brush, and a rag.
