I understand exactly why Mr. Wizard is happy. Been 10 months with my DEKA 145 Telecom AGM... and if at 60 to 70% SOC, on the EU2000i and the 30 amp MegaWatt, that 150AH Telecom surplus AGM might take 21 amps at a 14.4V setting on the MegaWatt 30. Discharge it slow, and charge it slow. No matter what, stuffing it with a couple of hours of Mega Watt every few days is what the battery likes, otherwise, it's just the 150W solar panel at 8.5 to 9 amps daily.
This battery needs to be pushed by the MegaWatt and pedestal, or generator, every 4 to 6 days, at the 20 amps plus, to really wake it up from time to time.
