How often should I replace my car battery?

The typical 12-volt car battery may last three to five years, depending on the type of battery, the driving conditions, and how well the battery is maintained.

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

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

What do I do about corrosion on my Yukon car battery?

To help extend the life of your battery, you should routinely inspect and clean the terminals using a baking soda and water mix, wire brush, and rag. Be sure to disconnect the battery cables before cleaning and check your Yukon owner’s manual for instructions on how to do so.
