Chris, Some of the information you listed is not quite correct. For example, all AGM batteries are not created equal and have different charging profiles. Odyssey ( remarketed by Sears as their premium marine battery) have an almost identical profile as a flooded cell while other are drastically different. The Bal Mar alternators in my 2000 3500 Open have Charles regulators which have about 7-8 different profiles and can charge almost any battery including AGM. I called Charles (also the maker of the battery charger on board) and talked to them about charging AGM batteries with the original alternators, regulators and battery charger. I have Odyssey AGM batteries installed and Charles was able to set me up with the correct dip switch settings on the regulator but the battery charger has no adjustments. Looking at the charging voltage from the battery charger, it works very well with the AGM's. And remember the alternators do not charge the batteries but the regulators do and that is what sets the voltage for charging, not the alternators at least on mine.
