Why doesn’t my 540i 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 cabin light at night. Stop by for a free battery test at your local Firestone Complete Auto Care and get a handle on your car battery’s health.

How long do car batteries last?

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 540i’s battery post?

The white, flaky stuff that can build up around your 540i’s battery terminals is known as corrosion. Acid leaking from your vehicle’s battery post can have a chemical reaction with the air, leading to an accumulation of the white, powdery substance over time. Corrosion can affect the flow of electricity between your battery and the electrical system in your 540i, possibly causing issues with electrical performance and starting. If left unaddressed for long enough, it may even cause your battery to prematurely fail.

How do I clean a corroded 540i battery terminal?

You can help prevent or get rid of corrosion by regularly inspecting and cleaning your battery terminals. Before cleaning your battery, see your 540i owner's manual to learn how to disconnect the battery cables. After disconnecting the cables, use a mixture of water and baking soda, a wire brush, and a rag to carefully clean the terminals.
