Battery terminals oxidize because of a chemical reaction between battery acid and metal. Exposure to hydrogen gas, moisture, and salt increases this reaction. Over time, oxidation leads to corrosion. This corrosion can harm the battery’s performance and disrupt electrical systems, causing potential issues for vehicle operation.
Preventing battery terminal oxidation is essential for maintaining an efficient electrical connection. To minimize oxidation, use a corrosion inhibitor spray on the terminals. Ensure that the battery terminal connections are tight to prevent moisture from entering. Regular inspection and cleaning also help reduce oxidation buildup.
Cleaning oxidized battery terminals is straightforward. First, disconnect the battery cables, starting with the negative terminal. Then, mix baking soda and water to create a paste. Apply the paste to the oxidized areas and scrub gently with a non-metal brush. Rinse the terminals with clean water and dry them thoroughly before reconnecting the cables.
