RJ's Fishing has a very true point. Feed adequate voltage to a battery bank and it will charge. For instance a thousand amp hours at 100' distance will charge just fine with 600 MCM wire. You do not want to know how stupendously large 600 MCM wire is.
NinerBikes has a valid point with some batteries being more stubborn to fully charge than others.
So rather than argue congratulate each other on both being "right". :)
RJ's combo works for him... cheap chinesium RJspecial charger at 14.4V with his batteries, mounted just below the charge controller and his group 27's. Same charge controller on my 6.5 amp 120w portable solar panel and a single group 24 was not getting my SG above 1.250 with 14.4V volts at the charge controller. An EQ session cleaned the cobwebs out of that battery with some baby sitting and a full 16.0V for about 20 minutes, after it started at 15.7V.
OP claims he killed a Trojan Group 31 AGM, which has even less internal resistance to charging fully than an open vent LA battery, and will charge fully on 14.4V vs 14.8V for the group 31 Trojan conventional.
Killing a Trojan battery, AGM or otherwise, in short order, takes some doing, misuse, or lack of charging fully or equalizing. It is in a shape and size, as demonstrated by a few around here, that is cranky and problematic to fully charge, it needs a lot of hand holding to get the EQ topped off.
