I bought this battery holder at a gun show a few months back and it has proved to be a real convenience. It holds 12 AA batteries securely. Since the holder can accept the battery either end down, I can also use the Battery Caddy to keep track of used vs new batteries. The batteries are held tightly so they do not rattle or make any noise in the caddy. In order to find the battery caddy in the pockets or pouches we keep it in, I added a 550 cord lanyard with a LED light. This simple modification makes the battery holder easy to find and easy to grab. Eventually I found this Uncle Mikes double magazine pouch which fits the Battery Caddy as if it was made for it.
