Why won't my Q45 battery stay charged?

A battery is in its final hour when it will no longer hold a charge. It may be getting old. Or, you may have been leaving your car doors ajar and the dome lights on during the night. Stop in for a free battery check at your favorite Firestone Complete Auto Care and learn more about your battery's charge.

What do you do with my dead Q45 battery?

How long can I expect my car battery to last?

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 Q45’s battery post?

The white, flaky stuff that can build up around your Q45’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 Q45, 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 Q45 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 Q45 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.
