Keeping your battery and the terminals clean is a key maintenance procedure to getting the most performance from your deep cycle batteries. Corrosion occurs when acid from inside of the battery makes its way to the terminals and connectors on top of the battery. The acid attacks the battery terminals and connectors, which if left untreated can reduce or disconnect power to the vehicle. In addition, untreated corrosion can lead to arcing, where the electrical current jumps an air gap resulting in a spark. This arcing can melt terminals, damage connectors, or cause ignition of hydrogen gas emitted during charging.
Fortunately, battery terminal corrosion can be easily cleaned with a special solution that neutralizes battery acid. The solution can be made by mixing one tablespoon (15ml) of baking soda to every 1-cup (250ml) of hot water. Apply the solution to the corroded areas of the battery terminals and use a wire brush or toothbrush to gently clean off any additional residue on the terminals. Once the terminals and wiring are clean, rinse the area with water to rinse any remaining solution off the batteries. Use some paper towels to dry the area.
To slow down the corrosion process apply some corrosion prevention spray to the terminals to coat them. Make sure to check the terminals approximately every six months and clean as necessary. Be sure to use protective gloves and safety glasses to prevent injury and ensure all connections are safely removed from the batteries prior to cleaning.
