I setup the Dometic Fridge on Friday to make sure it will run for more than 8 hours when receiving a constant 12-13 volts from the battery. I did not want to go on an 8+ hour drive, so I used a new auxiliary battery from my TT and kept it charged with my battery charger. I bought the charging outlet for my Builtright / 67 Designs phone holder, so it was easy to make the connections without cutting any wires.
I am happy to say it ran for 13 hours without issues. It does not get cold enough for food at 20 minutes, as was reported on the Raptor forum, but at about 1.5 hours it was in the 40s and my drink cans were cold to the touch. After several hours, there was condensation built up on the backside of the fridge. It was not a lot, but enough for me to feel it. The sides and front did not feel wet at any point during the day.
9:30 am Turned on >> Battery at 12.80 volts
9:30 am - 76F
10:10 am Battery at 12.39 volts >> put Battery on 12 amp charger
10:10 am - 56F
11:00 am - 47F
1:00 pm - 35F
4:00 pm - 32F
6:30 pm - 30F
7:30 pm - 29F
10:30 pm - 28F
10:30 pm Turned off >> Left the door closed overnight
8:30 am - 56F >> Inside surface and drinks still felt cold after 10 hours of no battery
At 7:30 PM (after 10 hours) NOTE: I reset the high low temp values several times to make sure it was not fluctuating too much.
