  • Why won't my 540i battery stay charged? A battery is in its final hour when it will no longer hold a charge. The battery may be too old. Or, you may have a habit of leaving your car doors open and the dome lights on during the night. Stop by for a free battery test at your nearest Firestone Complete Auto Care and learn more about your battery's charge.
  • What happens to 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.
  • How long can I expect my car battery to 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.
  • Why is there white, crusty buildup on my 540i’s battery post? The white, crusty stuff that can accumulate around 540i 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 remove corrosion from my 540i car battery? 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 540i owner’s manual for instructions on how to do so.
