Ok so my refrigerator in my camper took a crap and instead of buying a propane one I thought about this. Couldn’t I buy a 120 volt one and run it off an inverter connected to two deep cycle batteries? The batteries have a rating of 140 min @ 25 amps per hour X 2 is 280 min @ 25 amp hour. When you hook it up to an inverter does it just change the 12 volt DC batteries into 120volt AC and keep the same reserve capacity of 280 min @ 25 amps if that the case fallow my math. The fridge is 1.3 amps. 1.3amps divided by 25amps=19.23 times longer than at 25 amps. So 280 min reserve capacity times 19.23 times longer = 5404 min or 90.06 hours or 3.75 days of run time. Is this right or did I just completely over think this one???
