How long is a car battery good for?

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.

Why is there white, crusty buildup on my Sierra 2500 HD’s battery post?

The white, flaky stuff that can build up around your Sierra 2500 HD’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 Sierra 2500 HD, 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 a corroded Sierra 2500 HD battery terminal?

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.
