Buying a Replacement Battery for BMW 840i

Sadly, your BMW 840i won't last forever. Neither will its battery. On average, auto batteries last anywhere from three to five years. Don’t get stranded by your 840i’s car battery. Replace it regularly instead! Watch for signs that your current battery is getting too old or too weak. A slow engine crank, a blinking battery or check engine light, bloated battery case, corroded battery posts, or weak lights can all signal that your battery needs attention.

  • Why doesn’t my 840i battery stay charged? A battery is in its final hour when it will no longer hold a charge. It may be getting old. Or, you may have a habit of leaving your car doors open and the cabin light at night. Stop by for a complimentary battery check at your nearest Firestone Complete Auto Care and learn more about your battery's charge.

  • How often should I replace my car battery? 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.
  • What is the white, crusty substance accumulating on my 840i’s battery post? The white, flaky stuff that can build up around your 840i’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 840i, 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 corrosion off my 840i vehicle 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.
