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 ...

I had my battery go bad last summer. Here's the short version of the story.
I'm not sure what happened but all of a sudden I had a battery that was cooked, feeling very warm. I believe it developed a bad cell and the charger kept trying to bring it up to full volts. I was set up in a cg, hooked up to 50 amp power, and had to move that morning but neither the slides nor the Lippert 6-way leveling feet/landing gear would retract. Found out I had to have a working battery hooked up in order to retract the feet or for the slides to go in or out - Something to do with the large amount of electrical power required. It didn't matter that I was hooked up to good 120v. So I begged the CG folks to allow me to stay one more day until I could get a replacement battery (they were MOL booked up). I then drove 20 miles to a Walmart, got a new one, drove backed and installed it. At that point, I tried the slides and and they worked.
I should also state that all other 12v and 120v systems worked (including ac) and that I also tried plugging in to the truck - didn't work either.
This occurred last summer and things have been fine since then.
I have a 2014 Bighorn.
