Why is there white, flaky stuff around my 300’s battery post?

If you notice white, crusty stuff around the battery terminals of your 300, 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 300’s electrical system, potentially leading to poor performance, difficulty starting, and other issues.

How do I remove corrosion from my 300 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 300 owner’s manual for instructions on how to do so.
