We replaced a failing 7.5 cu ft Norcold absorption fridge with a 10.1 cu ft Haier residential fridge about 3 years and almost 20,000 miles ago. The fridge draws 1.2 running amps except for the few minutes the defrost function runs when it jumps to 1.8 amps. The LRA is listed at 6 amps, but measures at a momentary peak of 5.3 amps. A dedicated 850 watt PSW inverter handles the load with no complaints. The only time its been serviced was when a GE service tech replaced a recalled starting relay. Oh, and at 112 lbs, the Haier weighs about 15 lbs less than the Norcold.
So how long would a group 29 12V battery run this thing for?
