How long do car batteries 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 SC300’s battery post?

The white, flaky stuff that can build up around your SC300’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 SC300, 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 SC300 car battery?

Regularly inspect the terminals and clean them with a mixture of baking soda and water, a wire brush, and a rag. Disconnect the battery cables before cleaning to help avoid the risk of electrical shock. Always reference and follow the instructions in your vehicle owner’s manual prior to disconnecting the battery cables.
