Answers to Your 540i Car Battery Questions

Turn to Firestone Complete Auto Care for answers to all your car battery questions. If you have a 540i-specific battery question, visit your nearest store. Our technicians have the answers.

  • Why won’t my 540i battery hold a charge? A car battery that needs to be jump-started every time is as good as dead. The battery may be too old. Or, you’ve been leaving the doors slightly open and the cabin light at night. Stop by for a complimentary battery check at your favorite Firestone Complete Auto Care to learn more about the state of your battery.
  • What do you do with my old 540i battery? We recycle it! Nearly 100% of all lead-acid batteries are recyclable.
  • What’s the cost of DieHard batteries for BMW 540is? BMW 540i batteries can be affordable, especially when there's an available battery coupon. The best part is every DieHard battery comes with a free replacement warranty and extra coverage with DieHard Assurance.
  • What is the average lifespan of a car battery? 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 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.
  • How do I clean a corroded 540i battery terminal? Regularly inspecting and cleaning your battery terminals will help keep your 540i’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.
