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 ...

On 'most' RV's. You would have to check if yours is the same.
The fridge, and A/C, and co detector all need a constant 12v to them.
The fridge and A/C thermostats run off 12v.
(i.e. they run off your RV battery, not the shore power.)
If your coach battery has ow voltage your fridge and A/C will come on, but when they hit the temp set and shut off.....their thermostats can not turn back on again.
Detector has a 'low voltage alert'. If voltage drops from 12v they start beeping to alert you of low voltage.
