  • What is the white, crusty substance accumulating on my 740i’s battery post? If you notice white, crusty stuff around the battery terminals of your 740i, 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.

  • How do I clean a corroded 740i battery terminal? Regularly inspecting and cleaning your battery terminals will help keep your 740i’s electrical system running smoothly. Before cleaning, reference your owner’s manual for instructions on how to disconnect the battery cables.
