Why doesn’t my Flex 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 lights on overnight. Stop by for a free battery test at your nearest Firestone Complete Auto Care and get a handle on your car battery’s health.

What do you do with my old Flex battery?

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

How much will replacing my Ford Flex’s battery cost if I get a DieHard battery?

Ford Flex 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 long can I expect my car battery to 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 Flex’s battery post?

The white, flaky stuff that can build up around your Flex’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 Flex, 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 corrosion off my Flex vehicle battery?

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