Ah, that's pretty useless isn't it? Some shrink wrap on some unknown cell. A not uncommon practice though.
It the 'revival' turns out to be a dud, please take the time to cut off the shrink wrap. There may be writing on the can that will let us figure out the actual cell. You can also see the protection circuit that way.

I use the XTAR VC4 to charge these.

Well, it took FOREVER for the Trustfire to came in from China. I have no idea why this is, I order stuff from Japan and comes to me within a week.
Anyway, I tried the battery trick of putting the two positive ends together and running a wire across the negative ends. I did this for a few seconds, as outlined in the photo. It did not have any effect, the battery still will not charge in the included charger. The included charger charged the Trustfire battery when it arrived no problem.
So I would consider a better charger, but I noticed a comment made at the Battery University site that said:
"Do not boost lithium-based batteries back to life that have dwelled below 1.5V/cell for a week or longer. Copper shunts may have formed inside the cells that can lead to a partial or total electrical short."
So should I just consider this battery history? I don't want to invest in a charger, only to find out it's going to have no effect on the battery. I thinking I may as well just pick up another Trustfire as a backup and be done with it.
Thanks again for your relies.

If you have a hobby charger you can do a discharge test. Else use a trickle charger to revive them and see if they can hold a stable voltage for 24 hours. If not, then it is time to chuck them out.
