I just reently got 2 Ultrafire 18630's for my GLV2 super mini. 1 works great and the other not at all. At first I thought it was DOA but when I checked it on the vm it reads 3.6v. The only other thing I can report is there is a small protrusion on the neg side that is slightly larger on the not working battery which made for a snug fit in my pv. I pinched it slightly so it slides smoothly in the tube but still does not work.
Anyone have any ideas?
