Why is there white, crusty buildup on my S4’s battery post?

If you notice white, crusty stuff around the battery terminals of your S4, 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 S4’s electrical system, potentially leading to poor performance, difficulty starting, and other issues.

How do I clean a corroded S4 battery terminal?

You can help prevent or get rid of corrosion by regularly inspecting and cleaning your battery terminals. Before cleaning your battery, see your S4 owner's manual to learn how to disconnect the battery cables. After disconnecting the cables, use a mixture of water and baking soda, a wire brush, and a rag to carefully clean the terminals.
