Why doesn’t my 540i xDrive battery stay charged?

A battery that won't hold a charge is almost as good as dead. The battery might be old. Or, you’ve been leaving the doors slightly open and the cabin light at night. Stop in for a free battery check at your favorite Firestone Complete Auto Care and get a handle on your car battery’s health.

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 stuff around my 540i xDrive’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 540i xDrive 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 540i xDrive 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.
