How long is a car battery good for?

Car battery lifespan varies depending on a few factors, including driving conditions, accessories, how well it’s maintained, and the type of battery. On average, a car battery lasts about three to five years.

Why is there white, flaky stuff around my R320’s battery post?

The white, flaky stuff that can build up around your R320’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 R320, possibly causing issues with electrical performance and starting. If left unaddressed for long enough, it may even cause your battery to prematurely fail.

What do I do about corrosion on my R320 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 R320 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.
