what size, type, and how many batteries? What is the run time?
25 amps per hour while running.
Currently have 2 automotive batteries, not sure of size. That was my question, what size (amp- hour) would I need.Undrstand the 2.5 amps per hour, but refrige doesn't run continuously.
2 automotive batteries?
Yeah, that isn't going to cut it..
Group 24 RV marine battery tops out around 70 Ahr and at 50% capacity to save battery life is only 35 Ahr.
Contrast that to the basic 6V GC2 golf cart batteries, they will typically have 210Ahr-230Ahr and 50% of that is 105Ahr-115Ahr of capacity. They will hold up better to long deep discharging than starting batteries.
Good low cost source for GC2 batteries is Sam's Club or Cosco..
If using a "starting battery" for a car, that is a no go, those batteries will not hold up to long, deep draw down and will be toast quickly.
I use just one pair of 6V GC batteries for my home fridge conversion and am able to get 24 hrs before needing to recharge. We typically overnight without power and travel through the daytime and mostly camp at places with shore power.
IF you are planning to boondock for several days at a time, two pairs of GC batteries would be my suggestion from my experiences.
You could also add in some solar to help assist during daylight hrs which would cut down on the charging times using a generator.
