That was back in Jan 2014 where I had bought the Magnum MMS1012 1000W/50A inverter charger while at Quartzite. I only had the one Deka 8a24M, a 79AH AGM that was 5yo. Overnight the battery had run two Dometic CF35 fridge freezers. I ran 26 minutes in the AM making coffee and running the microwave until the LVD shutoff. Each device ran at ~700W.
Last year for a capacity test I wanted to draw 2KWh from the bank of two used 135AH Eaton Powerware batteries that were telco pulls.
It took a 5000BTU AC 4.5 hours to reach 2KWh.
