As far as I can remember, when it has been discussed here in the past, the charger incompatibility issues were with GEL batteries, not AGM.
I think the old chargers can charge AGMs.... but the newer generation of chargers include different charging profiles that designed to help improve the life of AGMs (and other type batteries using the specific charging profiles). Most new chargers have profiles for Lead Acid, Gel, AGM, etc. Its not that the older chargers wont accomplish the recharging task, but newer chargers may work and maintain the battery "better". ***Note... Individual users left to interpret marketing materials and charger claims individually.*** :huh:
