Refrigerator 110 to 12v

How long will a 110 refrigerator run on battery power that is converted to 12volt or will it even work?

Through an inverter do you mean?

Off of a standard lead acid?

If OP is referring to using an inverter, lot of variables I would guess. What is amp/hr rating of the battery bank. How much current does the fridge draw. Also, I would assume the ambient temperature would affect the current draw over a 24 hour period.

I am curious
How did you convert a AC fridge to DC?
Or is this the part you are asking will even work?

You don't convert the fridge to 12V. What you do is install an inverter thats hooked up to the batteries. The Inverter takes the 12V from the batteries and turns it into 110AC. You then can plug the fridge into the inverter and it runs like normal.
Problem is and depending on how much amp draw the fridge needs you can run the battery/s down fairly quickly.

Most people that run 110 fridges off an inverter have larger battery banks and solar. If you're plugged into shore power then you can switch the fridge back to 110. Or you can use the inverter and let the shore power charge up the batteries.

Yes I am aware

In the comments I asked if through an inverter and he kind of said no

Sure, it would work with an inverter and enough battery capacity. A lot depends on the fridge. A dedicated 12V fridge consumes a good bit of power, close to 100Ah per day. A 120V fridge will consume more, even with everything equal, due to the inefficiencies of converting between AC and DC. And a residential fridge can consume quite a lot indeed. So it really depends on your equipment and how you use it. I think if you guessed 200Ah a day you probably would be in the right ballpark.

I wouldn't do it boondocking unless I had at least a kilowatt of panels on the roof. And even then, it might be cutting it kinda close depending on *where* you're boondocking.

Back in the 1980's ... 3 way fridges were quite common...12 volt/ 120 volt/ propane...12 volt worked great for travel days running off the alternator.... but that's it,,,,

I'll try to clear up your question and answer it from my practical experience. I'm thinking you would like to run your absorption (110VAC / Propane) 'fridge on 110VAC using your battery as a power source? You would need to convert 12VDC to volts A/C. Have you or are you considering getting an inverter to do this function? The boiler in your absorption refrigerator uses a resistance element so it draws a lot of current. You would need a 15 amp circuit for it alone. That would lead to a minimum 2000 watt inverter. A single battery would not be enough to give any reasonable time. Multiple batteries with a generator or lots of solar power to keep them charged need to be considered.
I have two Li-ion batteries in my trailer with a 3000 watt inverter. I have run the 'fridge on 120Vac electric, a few short periods while traveling rather than turn on the propane. To do anything more would require a lot more battery power. I wouldn't recommend it as anything more than a short term back up.
To answer your question yes it would work but the expense, space sacrificed and trouble need be considered.
Another line of thinking is if you are asking about converting to a 12VDC refrigerator. That would require exchanging your unit out in it's entirety as it is a different system completely. The 12VDC refrigerators work like a house unit using DC electric to run a compressor. If or when I move to a new trailer I would look into one of those.
