Shopping for BMW M6 Car Batteries

Your M6 doesn't have an expiration date, but its battery does. On average, auto batteries last anywhere from three to five years. Check your battery regularly and replace it as needed so it doesn’t leave you and your BMW M6 stranded. Pay attention to clues that your battery is on its way out. A lagging starter, an illuminated check engine light or battery signal, bloated battery case, corroded battery terminals, and subpar electrical performance can all signal that your battery needs attention.

Plus, at Firestone Complete Auto Care, we’ll test your battery for free. Our equipment can see how much charge is left in your battery. Drop in for a free battery check and, if needed, get your BMW M6 a replacement battery. Car batteries are one of our many specialties!

  • Why doesn’t my M6 battery stay charged? A car battery that needs to be jump-started every time is as good as dead. The battery might be old. Or, you may have a habit of leaving your car doors open and the dome lights on during the night. Stop in for a free battery check at your favorite Firestone Complete Auto Care and learn more about your battery's charge.

  • How often should I replace my car battery? A car battery normally lasts three to five years, but this number can vary based on battery type, your driving habits, and battery maintenance.
  • What is the white, crusty substance accumulating on my M6’s battery post? The white, crusty stuff that can accumulate around M6 car battery terminals is called corrosion. It is caused by a chemical reaction between the battery acid and the air, which creates a white, powdery substance that can build up on the terminals over time. Corrosion can interfere with the flow of electricity between the battery post and the car's electrical system, sometimes leading to poor electrical performance, difficulty starting, and even premature battery failure.
  • How do I clean a corroded M6 battery terminal? To help extend the life of your battery, you should routinely inspect and clean the terminals using a baking soda and water mix, wire brush, and rag. Be sure to disconnect the battery cables before cleaning and check your M6 owner’s manual for instructions on how to do so.
