Top 540i Car Battery Questions

Get answers to common car battery questions, from Firestone Complete Auto Care. If you have a 540i-specific battery question, stop by your nearest store. Our expert techs have the answers you need.

  • Why doesn’t my 540i battery stay charged? A battery that won't hold a charge is almost as good as dead. The battery may be too old. Or, you may have been leaving your car doors ajar and the lights on overnight. Stop by for a complimentary battery check at your local Firestone Complete Auto Care and learn more about your battery's charge.
  • What do you do with my old 540i battery? We recycle it, taking care of both your car and the Earth.
  • What’s the cost of DieHard batteries for BMW 540is? You can find affordable 540i batteries by using one of our car battery coupons, when available. Plus, every DieHard battery comes with extra coverage thanks to DieHard Assurance and a free replacement warranty.
  •  How long do car batteries last? The typical 12-volt car battery may last three to five years, depending on the type of battery, the driving conditions, and how well the battery is maintained.
  • Why is there white, flaky stuff around my 540i’s battery post? The white, flaky stuff that can build up around your 540i’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 540i, 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 540i car battery? 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.
