I would leave the batteries in place. I'd add a trickle charger to them. Or add solar (which is what I chose).

There is no way anyone can give an accurate answer without knowing the brand and model of converter plus the brand and model of charger.

Why not just wire you batteries for a trickle charger so you don't have to remove them? That's what I did to mine. But, I prefer just using my solar.....

jdc1, how do you mean, exactly?

The converter is a WFCO model WF-8955PEC.

Still trying to figure out the charger.

Be careful if leaving it plugged in and using 30 to 20 amp adapter. A couple of bad experiences will not have me doing it anymore.

If your converter/charger is a Magnetec or a Parallax do not leave it plugged in. Most of the other brands, leave it plugged in. I love the Progressive Dynamics units. I leave my PD4645 plugged in 24/7/365.

The problem with WFCO is not that it won't go into float mode. The problem with that converter is it won't go into boost mode. As long as you don't boondock and try to fast charge your batteries every few days, the WFCO is fine.

Measure the voltage on the battery after a week of non use. 13.6 is normal, 13.2 is storage mode.

My preference is not to leave the RV plugged in all the time. There are several reasons for this. First, many (most) factory installed converter/chargers make lousy battery maintainers for long term use. Most of them have a tendency to overcharge and boil the batteries dry. Second, if you aren't using the RV, there isn't any reason to have all of the appliances, converter, TVs, etc... powered up waiting for a lightening strike or other power surge to hit them. The next couple of reasons aren't as big a deal, but still matter to some. There is no chance of forgetting to turn off the water heater, refrigerator, etc... if there is no power to the RV. There are always "parasite" power drains, the power it takes to run the clock in the microwave, keep the TVs in standby, etc...

It is true you could eliminate many of those problems by flipping the breakers to those appliances off, but that still leaves my first and biggest reason.

I kept our most recent TT plugged in for the first year and had to replace both batteries. Yes it's my fault for not paying close enough attention and not keeping the batteries topped off. After replacing the batteries, I installed a battery cutoff switch and wired in a battery tender quick connect directly to the batteries. Now when it's in storage, I flip the battery disconnect off and plug in the battery tender.

Thanks to everyone for the replies. I will have to read through them again and ask more questions. For now, Beaker, what experiences did you have with using a 30 amp to 20 amp plug?
