RV Battery Maintenance Tips

  • Check Water Level Monthly – Each cell should be filled with distilled water only after charging unless top of plates are exposed. If plate is exposed add enough distilled water to cover plate.


  • Keep Batteries Clean and Free of Corrosion – Use a mixture of 1/4 cup baking soda to 1 1/2 gallons water in spray bottle. Spray top, sides, cables, and battery rack with baking soda solution and let soak for 5 minutes.  A small brush will aid in removing any caked on dirt and corrosion. Carefully rinse with a low pressure flow of water being careful not to spray electrical components.  If you notice the baking soda mixture foaming, you will need a second application and thorough rinsing.


  • Check Battery Cables for Wear and Corrosion – Inspect battery cables for signs of wear and corrosion and replace if necessary.


  • Clean Battery Posts & Terminals – Depending on the age of your battery and battery cables you may need to clean battery posts and cable terminals with a wire brush cleaning tool.  Corroded connections can drastically reduce the life and performance of your batteries.


  • Use Battery Disconnect Switch – Today’s RVs have lots of electronics that continue to draw current from your batteries even when they are not being used. Some of the more common sources of phantom load are: clocks, stereos, LP-gas leak detectors, appliance circuit boards, and TV antenna power booster. You can eliminate phantom load by using a battery disconnect switch when not using your RV or when it is being stored.


  • Keep Batteries Properly Charged –  Lead acid batteries must always be kept fully charged.  A battery charger like the Battery Minder will keep your battery charged and extend it’s life.  Low charge will cause sulfation, which will rob the battery of performance.
