AGM batteries are more expensive and therefore most often the manufacturers proudly label them AGM on the top of the battery. In fact my AGM battery has AGM listed on the label in 3 places. The battery tender I use is effective and inexpensive, Deltran Battery Tender JR. You can type whatever is printed on the battery label in to google and search. You then will find the specs of the battery.
