So today I put all 3 AGM batteries into repair mode. They stayed in repair mode for the entire 4 hrs and then went to standby mode. Then I put them all in charge mode and all the lights lit up slowly 1x1. Then it started flashing green. So fully charged now and will kick back in if it senses that any 1 needs to be charged according to its parameters.
Not too shabby as I bought 1 in 2006, and it's been in 5 vehicles and still going. I bought the other 2 in 2010 and 2015.
