Will this charge an AGM battery?

Pretty tough to beat a Megawatt set at specified OEM absorbsion limit for AGM for small generators or BFL13's favorite that 100-amp charger.

Now leaving BFL's charger at say 13.5 volts, and re-charging 50% SOC batteries say 200 AH worth, what is the initial charge acceptance?

BFL?

Not tried that, but estimating close to 100 for a very short time and then rapid amps tapering. At 50% start, normally you would have the charger at 14.x for the Bulk Stage. In that case, it would likely kick off at close to 100, tapering very soon after that, but not so rapid a taper at 14.x.

With 200AH a good initial charging rate from 50% would be about 70 amps to get a short Bulk Stage, however that is dubious with a 2000w (1600VA) gen, so a 60 amp charger would be the way to go. That is for most AGMs and for Wets (Lifeline AGMs can take more of an initial charge rate than most AGMs, but you need the bigger gen to run the higher amps)

BTW the 100a charger in the photo has been sold, and I am using a similar model 75 amper these days. Can't take the 3000w Honda (also sold) in the MH, so now have a B&S P2200 (1700VA) gen, which can just manage the 75 amper.

EDIT--link above says AGMs can be at "any orientation"--wrong. Not supposed to mount them upside down.
