I use the AA version in several pieces of equipment, camera flash units and a prosumer grade digital audio recorder among them. With a few of these, the Duracells rechargeables are a tight fit, making smooth loading and unloading go not so smoothly. In a few units, I get worried I'm forcing the cover of the battery compartment to close it because of the length, and these covers are fragile in nature to begin with. I did break one cover because of all the resistance once closed. When I go back to my alkalines by Duracell or another well regarded brand, they fit easily.
I visibly can see they are tight because the skin of several of these batteries is getting stuck in the battery compartments and peeling up, so that just makes them more difficult to handle.
