Does anyone know where I might be able to pick up battery caps/covers/cases? The included battery with the camera always has one to protect the terminals from shorting out, but I just picked up a couple third-party batteries for the 40D and of course no such thing is included. With the old XTI I had three batteries and had the original cover plus one that came with my battery grip, and with at least one in the camera I didn't have any exposed terminals. As I didn't buy a grip for my 40D (nor do I really intend to), I don't have that secondary cover so that means at least one battery with exposed terminals in a bag full of sync cables and other assorted metal crap. I suppose I could always use a little bit of gaffer tape, but I'd rather avoid the mess if I can.
