Bulk-Absorption Charging Voltage
2 Concord 8D (258 AH each) Freedom 25 Inverter-Charger (130 amp) Trimetric 2025 Gauge I'm dry camping and charging my batteries. They were 30% discharged. My Concords call for 14.2-14.4v absorpti...

OP here. I'm back home now but won't be able to address this for a week or so. Anyhow, I've noted a number of comments for my reference and I appreciate all of this great input. I wanted to reply to a few things that have been brought up.
JRNY: I have a remote panel with dip switches. Power sharing is off. I set it for wet-cold as this is the closest profile to my Concord AGMs. These batts are about one year old and have never been discharged below 50%.
BEND & OTHERS: It's supposed to deliver the full rated current in bulk. I hadn't noticed the timer function determining when it goes to Acceptance (absorption).
MEXICO: Yes, they are AGMs.
SALVO: I will do as you suggest. Discharge to 50% and take readings at charger and batts.
SMK: The inverter works great. Never thought of just adding a charger. Probably save me a bunch of money. Good idea.
Anyhow, when I get to this I will relight this post and update with what I have found.
I plugged it in when I got home Sunday. The Trimetric indicates it now has a 95% charge and is only accepting point one amps. Thought it would be 100% after driving for five hours.
One more thing. Another guy on another forum has a similar rig to mine and also has the Freedom 25. He sees over 100 amps in bulk.
Thanks again to all for great comments.
