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.

Why is there white, crusty buildup on my 911’s battery post?

The white, flaky stuff that can build up around your 911’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 911, 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 911 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 911 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.
