Batteries are the highest-maintenance item on an RV. They tend to get abused because people don’t know how to take care of them, and the electrical system of the RV may not be designed to optimize battery life. Batteries will discharge over time, even if no lights or accessories are turned-on. Modern vehicles have various devices that consume a small amount of electricity from the batteries all the time, such as the memory for radio settings, engine computer, LP detector, etc. When a battery is left for a period of time without being charged, it will gradually be discharged. A partially discharged battery deteriorates much more quickly than a fully charged battery, so the normal life span of the battery will be shortened if it is not kept fully charged. A discharged battery will be completely ruined very quickly if left uncharged.
Water evaporates from batteries, and if the water level drops below the top the plates the battery will be ruined. Therefore, once a month, check the water in the batteries (if they have removable caps) and top-off with distilled water only to bring the level up to the “full” indicator. Distilled water is available in most grocery stores.
While you are looking at the batteries, take a look for corrosion on the cable terminal connections and on any metal surfaces around the batteries. Use battery terminal cleaner spray to neutralize the acid that is causing the corrosion. After it dries, coat the terminals and the metal areas with battery terminal protector spray. You can find both of these products in auto parts stores, or go here.
