I have absolutely ignored the "special" charging requirements for AGMs. My solar (55 amp Iota) and solar (Blue Sky controller) played well with my Lifeline and Universal AGMs. Simply plug and play. I should note, gel cell batteries do have different charge requirements, as I understand.
All three (wet-cell, AGM and Gel-Cel) have different charging voltages.
Wet-call and AGM are -close- and you can mostly get away with using a wet-cell setup on an AGM.
You will get better results with an AGM setup.
The Solar Charger that came with my Fox has an AGM settting and a Wet-Cell setting.
Progress-Dynamics states that their charger system works with both, but I have never looked into any possible changes in their required settings.
Personally on both Northwoods I've owned, I used 6V GC-2's. The 1999 required a minor carpentry bit, on the 2012 they were just drop-in.
