Amps jumping around on AGM finishing charge
At a battery temp of 81 degrees and a float charge of 13.33v, the charge was settling in toward .1 A when it started jumping around more and more. Still settling, but jumping from .02a to .15a. The ...

My AGM battereis come up against a "hard Stop" when they're fully charged. In other words, the ammeter in series with the AGM batteries reads a solid zero after so many hours of charging. Nothing I can do makes the ammeter show any more current flow into the batteries at that point. Even increasing the charge voltage back up to boost value will not make the ammeter show any charge flow once the AGM batteries are fully charged.
I've never seen any jumping around in current flow rates with my AGMs. That does sound strange ... I wonder if your ammeter or charger could have some instability somewhere in their cicuits ... IAW nothing to do with the AGM battery(ies)?
Hmm interesting. Mine will start to gas if I hit them that hard at the end. Amps do taper way down. On the 8 amp setting I am done when the volts jump up to the max charging voltage. On the 2 amp setting the amps will drop low but not stop and the volts don't spike. With the buck converter I can pick amp flows and voltages in between the two which I am doing now. I am trying to zero in on a real float voltage which can be on 24x7 if desired.
