How often should I replace my car battery?

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 3500’s battery post?

If you notice white, crusty stuff around the battery terminals of your 3500, 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 3500’s electrical system, potentially leading to poor performance, difficulty starting, and other issues.

What do I do about corrosion on my 3500 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 3500 owner’s manual for instructions on how to do so.
