Hi, I had a set of Rechargeable Ultrafire RCR123A fail on me at work. Thinking it was the light i tried it on another light. Nothing. Luckily i had a pair of 3.0v Cr123a in my locker before going out to the field. Well I got home and was going to throw them away. I tried charging them nothing. I used a multimeter nothing. Well I researched a bit and looked for PCB's I found the circuit board on the bottom of the battery. I carefully cut the plastic away from the bottom of the battery. I cut the postive running on the side of the batt. You can see the metal band on the side if you really look (try looking from the positive side first). Be careful not to cut into the protective inner plastic under the gray plastic. Remove the metal band running to the + first with small scissors then - . Try to remove halfway the running metal band alongside the batt. then use clear packing Scotchtape to wrap again around battery.
Now recharge the batteries. I tried these same ones and they were already fully charged according to my DSD charger. Now these just became unprotected so be aware to not overcharge them or overdraw them. It would be better to buy some more and try your luck on some new ones but when you only have one set of these better than throwing them away
