How long will my battery last on running fridge on propane?

[RickV]

Friday I will taking my 5ver to a location that doesn't have power. I will have a generator that I will run I'm while there. I will be leaving the place for 4 days and want to know if my battery (I only have one) will last running only my propane Frdge while I am gone or do I need to take my food with me when I leave? Temps will be around 80 during the day and upper 50's at night. I have one of those Dometic four door model refrigerators.

TIA
Rick

It depends on a lot. How old is the battery?

[RickV]

Around 3 years old. It will actually only be around 3 days. I am leaving in the afternoon on one day and returning 3 days later in the morning.

[davel1971]

I doubt it will last 3 days, as other stuff draws on it also

[bikendan]

a furnace alone will empty the battery in one night.
but the fridge will use very little battery power.
but it depends on how many parasitic power drains your RV has.

Thanks for the replies. I think I am gonna roll the dice and see what happens.

Your 4 door refer is located in a slide,this location Sometimes requires the Install of Fan/Fans for proper cooling! Some fans are installed by Factory some by owners! If your unit has these cooling fans they will also use 12V power,your gamble could end up with a Very Bad Smelly outcome! Youroo!!

Do a dry run at home if you can, then you will know before leaving. Put a few bottles of water in fridge and freezer.....

Turn off everything else but the fridge!
Pull fuses if you have to....
3 days should not be a problem.
My 2¢

Roll your dice if you will, but a trailer that big ought to have no fewer than two good batteries. IMHO

When in doubt we save commercial gel packs used for shipping perishable food and keep some in the freezer. We move some of them into the refrigerator when leaving unit for several days. The bags usually last 2 days without refrigeration.

I am not sure but our batteries went down fast with just the frig on until we turn the switch on the frig to gas only instead of auto. Seemed to make a world of difference! I think something keep searching for 110 and used up the battery?

Most fridges have a 12v heating element that keeps condensation from forming at the doors. This is the biggest draw on the 12v system by the fridge. I disconnected the wire to this heater on my Domestic fridge to extend my battery life. (It also disconnected the light in my fridge.)
The fan on the heater is also a big load on the battery. One of those portable propane heaters works well to heat the trailer, but leave a window cracked for ventilation.

Add plenty of ice in the freezer and frig. Our smaller frig stayed cold for 4 days on propane. We had to pull out to avoid a flood. No time to take anything out but I always keep ice in the freezer and I think that saved the day, or at least the frozen hot dogs!
