Okay, having read the above, I'm now concerned about my batteries. I bought 6 of the AW 3100 batteries and they cost $16 apiece. Now at least 2 if not 3 have the outer black liner torn off. Are you saying I should discard them? I definitely will if necessary.
In my opinion and for this light only, I would not use an unprotected cell because of the extremely tight clearance between cell and body/tube and the sharp tube entry geometry which increases the risk of label/insulation failure which Could lead to a rapid vent with flame. At least with the protected cell, the over-discharge should kick in and prevent this if all is working correctly.
If you have a light with more clearance, you could repair the label or remove the original shrink wrap and apply new wrap carefully with a heat gun.
Even with "safe" cells, I've seen the potential for rapid vent without flame with the CGR cells today. I would guess the same might be true of IMR's but I don't know that for a fact. At a minimum, if these safe cells dead short, they will be ruined.
