Running stereos, clocks, water pumps together can drain the batteries.Ī fridge ideally wont take much battery power but together with all other smaller appliances it can result in battery getting drained.Ī new battery, if not charged fully will result in its draining earlier obviously. You run an air conditioner, and the battery charge is gone. Or you have too many smaller appliances that run together and collateral draw is higher.Ī carbon detector or the PL detector can drain the batteries faster. What about batteries that new and in good conditions? Well, the obvious reason is some appliances are taking too much amps. So, there is no real direct solution for this as the batteries are either old or have been through worst conditions like overcharging or undercharging or have gone through freezing. Undercharging is one of the prime reasons why batteries fail earlier than expected. So, stay charged above 20% or better above 50%. At times that is okay but going below 20% is definitely not good to do. One point while charging the batteries you need to keep in mind is never drain your batteries below 50%. If it was your first try to charge the batteries, then there is good chance that the converter is not the one that is designed for charging the house batteries. This normally happens when the battery is not hooked up correctly and the fuse blows because of that. So, as first troubleshooting step check for loose wiring connection. The other most common reason is the fuse of the charger system blown. It could be because of wiring issue or because of the on-board charge not functioning. The battery could be an older one and is no longer working. This could happen because of number of reasons. Why does the RV battery not chargeĪ battery not charging even after connecting to the shore power is an issue many of us face. But, if you want to run devices that draw larges amps then be prepared to charge batteries more often. A minimal usage of lights and other smaller appliances can give you long hours. It all depends on how many appliances are running. Remember, no two rvers will have same usage. One can also have multiple batteries but use one at a time, this helps in planning if you have longer time to cover. But, weight of the RV battery is also a factor to concerned about.

One another option is to connect multiple batteries in series connection and get more hours.
