With the parasitic drain, you have to leave them on some kind of charger or disconnect altogether.

I leave our TT plugged in 24/7 because I also run a de-humidifier inside 24/7. Never a problem.

I use a pair of 6 volt golf car batteries and top them up each month even if just a drop or two. Just be sure not to overfill and try to use only distilled water.

Ex telco

Being an ex telco worker I tend to be overprotective of my wet cell batteries. Part of my winterization process is to remove the battery and bring it into the garage. Keep it on the bench, top off the water, charge it up and put it on the trickle charger (Harbor Freight about $8). Makes em last a good long time.

Nothing is on inside but was wondering if it keeps the batteries topped off while plugged in or if it is actually bad for the batteries. I don't want to cook them dry but, if it doesn't trickle charge them at all, no need to keep the microwave clock functional. Thanks for your knowledgeable replies!!!
RV's of this class that have the factory converter/charger are low end (had to change/upgrade mine) as the low end models the factory installs do not have the proper type of charger to just leave plugged in and forget. They can damage the battery if left alone.
So i would just unplug the coach, take out the battery and put it in your basement (or somewhere warm and dry) it will freeze pretty easy, with a float charger clipped on it the battery, and just reverse the process in the spring (or month) when you leave again.

Hope this helps and Happy Camping

My batteries are now 8+ years old being maintained by the "low end" converter, plugged in 24/7 and they still hold a charge. We camp without hookups half the time and the batteries still perform well. I do keep the water level up, but only have to add a couple of times a year.

Leave plugged in or not?

You really need to get the build sheet with the model number of your converter and all your other equipment. For the converter, that will tell you if you have the type that can be left plugged in long term during non-use (will automatically shift to float mode) or not. Or you can look on your WFCO for the model number and Google it. I see directly conflicting comments above as to whether this particular unit can or cannot be left plugged in full time.

By the way, you will have very little battery trouble with storage for one month. I really can't see where it's worth the bother of pulling out the battery. If in doubt, plug it in for a couple of days then unplug it. Two weeks later, repeat. Two weeks later repeat then hit the road. Check battery water levels each time.

IMO, if you are going to leave the battery (s) connected, they need to be on charge 100% of the time. I've sulfated a battery in less than 1 1/2 years by unknowingly charging and discharging it too much due to the parasitic drain. So given the alternatives, keeping it on charge all the time is what I do now. The WFCO is definitely not overcharging on my TT. I'm definitely going to put a disconnect at the battery so I can stop the parasitic drain however.
