Why won’t my 325i battery hold a charge?

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 to learn more about the state of your battery.

What do you do with my old 325i battery?

We recycle it! Nearly 100% of all lead-acid batteries are recyclable.

What’s the cost of DieHard batteries for BMW 325is?

BMW 325i 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 often should I replace my car battery?

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.

What is the white, crusty substance accumulating on my 325i’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 325i 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.

How do I clean a corroded 325i battery terminal?

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.
