Pete,
Sorry they're not working for you. I should have charged them before I sent them. My apologies for that. They are a bit old, but haven't really seen much use, since I had 5 of them, and only 1 light they would work on. So most of those I sent out had only been through one or 2 cycles. They should be fairly fresh. Sometimes the charger can make the difference, since these are protected cells, and a bit longer than some, I use my 18650 charger with some spacers, and this setup seems to work well for those batteries. If you still can't get them to work, let me know and I'll take care of you. But hopefully the pure awesomeness of that knife will make up for any disappointment you may feel ATM:thumbup:
