I contacted Deltran and asked which Battery Tender I should use for a absorbed glass mat (AGM) battery that is in our cars. They told me to use their Battery Tender Plus Gel unit.

I use it religiously as my car is driven sporadically. And still, my battery died and had to be replaced at 10 months, 7100 miles.
