A battery’s lifespan is determined by a number of factors, including the quality of the battery and how it is used. That said, a good rule of thumb for estimating the lifespan of your battery is to divide its amp-hour rating by 20.
The problem with this estimate is that it does not take into account how you use your trailer and what type of battery you have. For example, if you use your trailer in cold weather or if you use it to power appliances like an air conditioner, then your mileage will be less than what this estimate would predict.

How do I know when my RV battery needs to be replaced?
If it seems like your battery is losing power faster than normal, that is a pretty good indicator. Check your charge periodically and keep track of any fluctuations or drops in charge. If it seems like it is draining even when not in use, don’t change it. Replace it.[3]
Is it OK to leave your RV plugged in all the time?
For RV rentals, when you’re out on the road, or for any short term battery usage, you should have no problem leaving your RV plugged in 24/7. If you’re renting an RV from a company like Cruise America, you won’t have to worry about overcharging your battery.[4]

Does RV fridge drain battery?
An RV refrigerator will run off of the battery if your fridge model is set up for it or if it uses propane too. An absorption fridge will run on batteries only for about 3 hours but if using propane too it will last for weeks. A residential RV fridge will last for about 12 hours on batteries.[8]
How do you test a travel trailer battery?
Voltage Test This test is very easy, just place the leads on the positive and negative terminals and have the multimeter set to DC volts. Based on the reading you can determine the state of charge. A fully charged 12-volt battery will read around 12.6 – 12.8 volts, half that for a 6-volt battery.[9]
Will plugging in camper charge battery?
Fortunately, the answer is yes; your RV house battery will charge while it is plugged into shore power. Your RV battery will charge when an external power source is connected and providing power to your RV.[10]
How do I keep my RV battery over winter?
Store the battery in a warm, indoor location like a cellar (don’t rest the battery directly on the floor. Use cardboard or other material as a mat). Attach a battery maintainer to keep it charged during storage. Check your battery monthly to make sure it is fully charged.[11]
