This is a long shot, but I still have until the end of January to return this light to Amazon! Like the title states, I am looking for a spare battery for this light. If I can find one, I will probably keep the light. I actually emailed Thrunite and they said the lights head is glued down and they do not have the battery. My lights head easily unscrewed and I have easy access to the battery. I have included photos. As you can see, the top of the cell is not a standard configuration. The negative and positive part of the cell are on top of it! A standard 14500 or AA does not work. If I put any standard 14500 in it, the led just slights lights up. I actually have an old Fenix light that came with a 18650 cell that was like this. Have any of you ever seen a cell like this and have any ideas where to get one? Thanks in advance for any assistance here!
