“Cleaning. The contact terminals are prone to corrosion. Prevent this by cleaning the terminals using either a wire brush, a special circular battery brush, or even an old toothbrush soaked in baking soda. After cleaning and reassembling, prevent further corrosion by applying dielectric grease to the post and cable ends.
Maximize your RV’s battery life further (not to mention its overall performance) by having it checked by a reliable provider of Folsom or Roseville RV services like Prairie City RV Center. Your vehicle is a significant investment, so it’s wise to keep it and its components in tip-top shape.”
