Charging Batteries

Ooops... I left my switch that kills the house batteries on.. now the house
batteries are dead.
Am I correct that if I plug in the RV my whatever thingy will charge my
If so when I plug in will I be able to use the lights and the frig? and the
120v plugs (TV etc.) will I have to wait for my batteries to charge and
since they are dead, dead, dead, how long will it take to charge up 2 batteries.
97 Tiffin Allegro Bay 35' Chevy.
Or am I gonna have to replace them as they are totally dead.?
Does the frig on propane need battery power.. I think so as the buttons and
lights on the front require it.

Am going to a friends on Monday & will have only 110 but can plug in until Thurs a.m.,and then to an event Thurs -Sun where I will have 50 amp.
at an RV park.

Any info will be helpful.

Hope I explained this so you can understand it.

We'll be friends until I'm old and senile, then we'll be new friends.

I would use an outside battery charger to bring the batteries up to at least a fair charge instead of relying on the coach charger to do the job. Not that the coach charger wouldn't work but it might relieve some stress on it.
An hour on fast charge from a good charger should get you back into business. I would start out with a slow charge for a few minutes then increase the rate. Just because the batteries are totally dead doesn't mean they need replacing.
You will be just fine.

Check the electrolyte level in the batteries to be sure the plates are covered.....don't fill them all the way up until after they are charged. After they have been charging awhile feel them to see how hot they are getting. If they are more than warm, they could be shorted and need to be replaced.
