Using shore power with bad batteries
I have two batteries that only show 11v on my multimeter. I have tried to charge them up but can't get them to read above 11 volts. Is it safe to use the RV occasionally plugged into AC power until I ...

At campgrounds you meet all sorts of folks (as we all know)and some just don't want to know how some things work, while being interested in other things. IMO that is allowed. A person can get so he feels his brain is full up, and just refuses to add more, because he is RVing to try and relax some.
So IMO if it is batteries or solar or whatever about RVing somebody just doesn't want to know, he should be permitted to do that. He gets one chance while you explain it, and if his eyes glaze over, that's it. That does not make him a bad person. :)
Never said anyone was "bad" but this isn't "brain surgery" or "rocket science", just look for a simple standardized BCI number which IS somewhere on the battery label. Then it is simply just match and go..
If one is not up to that, then take the battery to say AutoZone, Pepboys, or any other place that sells automotive lead acid batteries and let the techs there make the match.. You DO have to take the battery with you to get the CORE CHARGE removed from the sale anyways.
Additionally, I can't see the reasoning as to why one would "wait til spring" or "wait a few months" to replace the battery, do it now and be done with it.. That battery will stay perfectly fine and will stay fresh those few months especially when you couple that with multi stage charging converters.
Letting a partial or fully discharged battery sit around in freezing weather is taking chances of the electrolyte FREEZING which may crack the battery case causing acid damage to said RV..
Fully charged batteries will not freeze..
