Why won’t my Mustang battery hold a charge?

A battery that won't hold a charge is almost as good as dead. The battery may be too old. Or, you may have been leaving your car doors ajar and the lights on overnight. Stop by for a free battery test at your favorite Firestone Complete Auto Care and get a handle on your car battery’s health.

What do you do with my old Mustang battery?

What is the average lifespan of a 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 Mustang’s battery post?

The white, flaky stuff that can build up around your Mustang’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 Mustang, 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 remove corrosion from my Mustang car battery?

You can help prevent or get rid of corrosion by regularly inspecting and cleaning your battery terminals. Before cleaning your battery, see your Mustang 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.
