How long can I expect my car battery to last?

A car battery normally lasts three to five years, but this number can vary based on battery type, your driving habits, and battery maintenance.

What is the white, crusty substance accumulating on my K10’s battery post?

If you notice white, crusty stuff around the battery terminals of your K10, 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 K10’s electrical system, potentially leading to poor performance, difficulty starting, and other issues.

What do I do about corrosion on my K10 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.
