Did you find a shorter length 14500 L/I battery that fit the 2100's battery holder. My original battery is only 43 mm long (tall), and the frame it sits in does not appear to allow anything longer.

I've got my 2100 apart, but the original battery is only 42-43 mm in length and the frame it sits in will allow nothing longer. Most of the 14500 L/I batteries I'm seeing say they're 50 mm long. Has anyone found a short length 14500 that will fit these specs?
