I was under the impression AGM batteries do not require a special charger but will benefit from a smart charger.

"Lead-acid batteries that have the electrolyte absorbed into a fiberglass mat (AGM) take generally the same charge voltages and charging schemes as a regular ol' sloshy flooded (FLA) battery."

"HOWEVER - batteries which have the electrolyte gelled with an additive (GEL) usually DO require a special charger, because they A) require a bit lower charge voltage, and B) are much more sensitive to overcharging than FLA or AGM.)"
