  • What do you do with my old M440i battery? We’ll recycle your car battery for you!
  • What’s the cost of DieHard batteries for BMW M440is? BMW M440i 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 is a car battery good for? You can usually get three to five years out of your car battery. However, battery type, how well you maintain your battery, and your driving habits can all affect your battery’s lifespan.
  • Why is there white, flaky stuff around my M440i’s battery post? A chemical reaction between battery acid and the air can cause a white, crusty buildup to form on the terminals of your M440i car battery. This buildup — known as corrosion — can impede the flow of electricity and cause a range of issues, from poor performance to premature battery failure.
  • What do I do about corrosion on my M440i 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 M440i owner’s manual for instructions on how to do so.
