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.

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 Century owner’s manual for instructions on how to do so.
