Fridge run time on LP & Batteries

Does anyone know how long the fridge will run on LP not connected to shore power with the batteries only? I have two batteries in a BH with a standard fridge.

Not sure but it is less than a week, learned that while out of town, came back to a warm fridge.

Obviously, longer if you have solar panels on the roof.

Unless the weak point is the amount of propane you have.

It depends on several factors. The warmer the outside temperature the more the fridge has to run to keep it cool. Also it takes the fridge 1 hour to recover from 1 minute of an open door. (I just took an RV refrigeration course and learned that fact) So there is not a pat answer. Take a look at these videos...
