How long do car batteries last?

A car battery normally lasts three to five years, but this number can vary based on battery type, your driving habits, and battery maintenance.

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

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

How do I clean a corroded Century 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 Century 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.
