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 stuff around my RX350h’s battery post?

The white, flaky stuff that can build up around your RX350h’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 RX350h, 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 RX350h car battery?

Regularly inspecting and cleaning your battery terminals will help keep your RX350h’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.
