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...

Multiple batteries, and a meter that is probably not synched correctly. Thirty percent deducted from a question mark leaves a whole lot of questions.
A healthy 8-D discharged 50% will suck 130-amps.
Like I have been preaching, managing AGM batteries requires patience and never ASSSSSSSSSSSSume meter calculations remain calibrated for months on end. They can't, they won't, and that is a guarantee.
Correctly performed RESTING VOLTAGE temperature compensated is the best state of charge indication. But like with flooded batteries resting voltage is at best approximate. There is no way to access the chemistry of a VR battery.
From appearances the charger is leaning on a shovel. The charger goes to max rated amperage until bulk voltage limit is reached or there is a charger or connection problem. A or B there is no C
