What to put on automotive battery terminals to prevent corrosion?

To prevent corrosion on golf cart battery terminals, you can use various products and methods designed to inhibit the formation of corrosive deposits.

Here are some effective options to protect your golf cart battery terminals from corrosion:

Battery Terminal Spray or Coating:

Battery terminal sprays and coatings are specifically formulated to prevent corrosion on battery terminals. They typically come in a spray can and are easy to apply.

After cleaning the battery terminals, spray a thin, even layer of the protective coating over the terminal and cable connections. Follow the product instructions for the best results.
These products create a protective barrier that helps to repel moisture and corrosive substances.

Petroleum Jelly or Dielectric Grease:

Applying a thin layer of petroleum jelly or dielectric grease to the battery terminals can act as a barrier to prevent moisture and corrosive materials from making direct contact with the terminals.
Make sure to coat the terminals and cable connections evenly, but don’t apply it too thickly.

Felt Battery Terminal Protectors:

Battery terminal protectors are felt washers or pads that you place over the battery terminals before attaching the cable connections.

These protectors are designed to absorb and neutralize corrosive materials, keeping the terminals clean and preventing corrosion.

Anti-Corrosion Washers:

Anti-corrosion washers are specially designed washers made from materials like lead or felt, which can prevent corrosion from forming on the terminals.
Place these washers between the battery post and the cable connector before securing the connection.

Baking Soda and Water Solution:

If you want a DIY solution, you can create a mixture of baking soda and water. Mix a tablespoon of baking soda with a cup of water until it forms a paste.
Apply the paste to the terminals and cable connections and use a brush or toothbrush to scrub away corrosion. Rinse with clean water and dry thoroughly. Afterward, you can apply a protective coating as mentioned above.

Regular Cleaning and Inspection:

One of the most important preventive measures is to regularly clean and inspect your battery terminals. Remove any existing corrosion using a wire brush or battery terminal cleaner and a mixture of baking soda and water. Rinse and dry the terminals before applying a protective coating.

Remember to take safety precautions when working with batteries, such as wearing protective eyewear and gloves, and always disconnect the battery or turn off the power to the golf cart before servicing the battery terminals. Preventing corrosion on battery terminals will help ensure a longer life for your golf cart’s electrical system and maintain optimal performance.
