Richard,
I found this on Marinco's website:
http://www.marinco.com/files/support/product/specsheets/2620A_08.pdf
They claim to work with sealed lead acid, AGM, and Gel batteries. There is no selector switch or anything, so I'm now sure how it determines what charging curve to use. Maybe it uses some kind of compromise, in which case it may not be ideal for your AGMs.
Though I have very little direct experience with them, I hear AGMs are a little more fussy about charging than wet-cells.

They are a little small for that application, but I wanted something that my 900W Honda generator could handle. I have tried motoring while running the Honda and they didn't seem to mind, though I only ran for a half hour or so. I'll do more extensive testing of that mode next summer.

The batteries were flooded lead (not sealed) and I rarely had to add any water. I don't know if that means anything other than the charger was not boiling the batteries :-).
