  • What do you do with my old 735i battery? We recycle it! Nearly 100% of all lead-acid batteries are recyclable.

  •  How long do car batteries last? Car battery lifespan varies depending on a few factors, including driving conditions, accessories,  how well it’s maintained, and the type of battery. On average, a car battery lasts about three to five years.
  • What is the white, crusty substance accumulating on my 735i’s battery post? The white, flaky stuff that can build up around your 735i’s battery terminals is known as corrosion. Acid leaking from your vehicle’s battery post can have a chemical reaction with the air, leading to an accumulation of the white, powdery substance over time. Corrosion can affect the flow of electricity between your battery and the electrical system in your 735i, possibly causing issues with electrical performance and starting. If left unaddressed for long enough, it may even cause your battery to prematurely fail.
  • What do I do about corrosion on my 735i car battery? Regularly inspecting and cleaning your battery terminals will help keep your 735i’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.
