I also have one of these but I don't use it for my AGM anymore. The only reason is I have the larger CTEK 7002 for my Walmart H7 AGM and an Odyssey 15 amp (made by CTEK) for my Odyssey batteries. I use the MXS 5.0 for my wife's flooded.

I've also had 12 years out of the the last two car batteries but keeping them charged is only part of the equation. I'm in a cool climate and no one would expect to get that sort of battery life in a hotter climate. Needless to say I must be doing something right so I've bought pretty much the exact same AGM battery as a replacement. The bike is old with zero current draw so that's how I get away with not having it permanently hooked up to a maintainer.

That is the exact charger I have. In fact I just completed the annual AGM Recondition mode on my motorcycle battery yesterday. I have three CTEK chargers for various machines and they are excellent.

Factory AGM in my '01 Road King went 10 yrs. I pulled it due to age not lack of cranking at the time having less battery knowledge.
Put an Odyssey in then in '11, it's still in there today at 14 yrs old. Both batteries were on Battery Minders whenever it was in the garage.
Makes me wonder how long that factory East Penn battery would have lasted.

AGM batteries do use liquid electrolyte but it should be mostly absorbed into the absorbent glass mat between the plates. I've never bought an AGM for a car but some motorcycle AGM's are distributed dry with a measured amount of electrolyte to add. Perhaps the dealer did that just before sale although I think this arrangement is less common than it once was.
I've never seen an AGM battery that didn't have AGM printed on it plain as day so looking at it may answer the question.
I've also never bought a new battery that was fully charged so the first thing to do before fitting is to charge it. I monitor the charging voltage until it reaches 14.5 volts and maintain that voltage for at least one hour. The 20 Ah AGM I just bought for the bike took two hours of charging to meet that criteria.

Post a picture of the top and the side that has a molded date or production number.

Find one that has an actual AGM mode.
I like batteryminder.
