0.0 amps at 15.1v on an AGM
I've been using the 0.5% of capacity at 14.46v as an indicator as to when to stop charging my Northstar group 27 AGM. But I have also let voltage to stay at 14.46 overnight, and the Ammeter reads 0...

I do notice after a bunch of low and slow recharges, that it takes forever for amps to taper to 0.42, much longer than normal.
And when I do plug in the meanwell to hold it at 14.4v long enough to taper to 0.5% of capacity, it still behaves badly, well, not as well as it does after a High amp recharge.
So Sometimes absorption stage lasts 3 hours, sometimes it takes 8 to 10 hours after a bunch of low and slow 50 to 97% recharges.
How is any automatic charger today supposed to account for every battery's characteristics when there is no programmable amperage threshold?
Time for nailing that chicken to the front door I guess.
