What is the white, crusty substance accumulating on my NX300h’s battery post?

If you notice white, crusty stuff around the battery terminals of your NX300h, 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 NX300h’s electrical system, potentially leading to poor performance, difficulty starting, and other issues.

How do I remove corrosion from my NX300h 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.
