Rogue MPPT, 490W and charging mysteries
Now that we were finally all in one place - me, Rogue 3048 and my rig - it was time to have some fun. 1)Battery: old starter, tested beyond dead, plates above the water. No wonder, 8 months in Mex...

I am concerned about the 12.45V = 75% SOC.
Here is a Deka Manual pdf. On page 2 they show 12.60V = 75% SOC. That would put your 14.45V halfway between 75 and 50 for 62.5%.
Is this 45978.pdf the battery?
Looking at the chart Shelf Life & Storage you can see the 60% line and how you may have crossed the line. What if the battery was two months older or only 90% charged when put in storage?
That 62.5% estimate is dangerously close to the 60% charge may fail... threshold and likely explains why 1 AGM is not charging to float. I wish I could help more, but I have not been there with my AGMs.

P.S. I just saw your amended post and await your report that all three AGMs are ready for service. :)
