Lead acid batteries get an extended life if they are kept cold. During the spring/summer/fall charge it overnight every 30 days. Self-discharge slows the colder the battery is so you can get away with doing it only once in the middle of the winter.

Since you'll be leaving your camper plugged in you'll get the best of both worlds - extended battery life since they'll be cold, and no need to remember to recharge. I agree you should check the water level often until you are sure your converter isn't boiling it off.

All I'm saying is if you want to spend money every spring for a new battery leave it in the trailer and do nothing to it.
Thanks Mark0224, I really didn't know the temp that will be bad for them. If I wasn't plugged in 24/7 I would never think of doing that. I have also learned that I have to start my truck atleast one a month also, thanks for the info..
