How long is a car battery good for?

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 R20 Suburban’s battery post?

If you notice white, crusty stuff around the battery terminals of your R20 Suburban, it's likely corrosion. A chemical reaction between battery acid and the air can create a white, powdery substance that builds up over time on the terminals. This buildup can interfere with the electrical connection between the battery and your R20 Suburban’s electrical system, potentially leading to poor performance, difficulty starting, and other issues.

How do I clean corrosion off my R20 Suburban 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 R20 Suburban 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.
