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 ...

Jim, when your AGM(s) start to out-gas if you hit them at the end ... does the ammeter still show current flow into the battery(ies) while the out-gassing is occuring?
The reason I ask is ... maybe my AGMs are actually out-gassing when they're up against the full charge "hard-stop" I see along with the zero current flow shown on my ammeter.
Intuitively (not remembering the electro-chemical reactions/equations involved), it SEEMS that the outgassing would/could NOT occur unless current flow was occuring at the same time. The energy to drive the outgassing process has to be coming from somewhere ... and I doubt that only the electromotive force field from a charger ("charging voltage") could cause the out-gassing process with zero electron flow indicated. I could be wrong, though ... I've long since sold my chemistry textbooks!
