Why won't my Z4 battery stay charged?

A car battery that needs to be jump-started every time is as good as dead. It may be getting old. Or, you’ve been leaving the doors slightly open and the dome lights on during the night. Stop by for a free battery test at your favorite Firestone Complete Auto Care to learn more about the state of your battery.

How long can I expect my car battery to last?

The typical 12-volt car battery may last three to five years, depending on the type of battery, the driving conditions, and how well the battery is maintained.

What is the white, crusty substance accumulating on my Z4’s battery post?

The white, flaky stuff that can build up around your Z4’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 Z4, 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 Z4 battery terminal?

Regularly inspecting and cleaning your battery terminals will help keep your Z4’s electrical system running smoothly. Before cleaning, reference your owner’s manual for instructions on how to disconnect the battery cables. Once the cables have been disconnected, gently clean the terminals with a mixture of water and baking soda, a wire brush, and a rag.
