Yes, the BMW 105AH battery that you posted is an AGM battery. It says so right on the battery.

When I replaced mine back in Jan/2023 (see pics below)...with my BMW CCA discount...it was $227 out the door (with $18 core charge return). All the other H9 class size batteries being sold by other vendors in my area (at the time) were only 100 AH and they cost more. Batteries Plus did sell a 105 AH Duracell 95R/H9 battery...but they wanted over $300 for it.

The other thing that I appreciated with the BMW branded battery is...it came with a little black elbow and additional plug in a little plastic baggy...which is needed to connect the new battery to the car's vent tube and to PLUG the other vent hole on the other side of the battery. You need to do this if your battery is enclosed inside the trunk or below the rear seat...any off gasses from the battery need to be vented to the exterior of the car and not released inside the car/battery enclosure.
