    Possibly. Which terminal is the strip attached to? What is the metal it's touching attached to? How many cells are there?

    Isn't the strip on a protected cell attached to both + - terminals? If it touches the in side of a battery tube in a flashlight would that harm anything? Would it make a difference if a light uses 1 or 2 cells?

    I'm asking because I saw Sanyo protected cells on another site that have that strip exposed. I don't know if those are safe to use or not.
    NO! I don't know why DX screwed up the site so badly.
    Ask them.

    On the older style negative protected cells, the long strip that runs up the side is connected to the positive terminal, and there is a very short strip/jumper which is connected to the negative terminal. If you peel off the outer wrapper, the positive terminal should still be insulated with a piece of golden Kapton tape, so it won't accidentally short out on the inside of a flashlight battery tube.

    Is that strip completely exposed? They didn't use any kapton tape on top of it? How about a second strip of kapton below the positive strap?

    [edit]The last line of defense preventing a short will be the anodizing inside the flashlight tube. But it would be a REEELY bad idea to depend on that to prevent a short. A shorted lithium cell in a sealed aluminum tube is basically a pipe bomb. I would put some kapton tape on the positive strip and re-heatshrink wrap it.
    What's up with the scrubbed LED driver IC markings?
    What are they trying to hide?

    That would short out the battery and be at least as bad as anything you're imagining from the strip touching anything else.

    It looks completely bare, and neither the top plastic insulator or the PCB on the bottom are covered with wrapping.

    It looks like the PCB was added to an already wrapped battery, with no wrapping afterwards. They were listed today on that "other" site.

    Heheh, yeah, I guess that strip couldn't be attached to both terminals. Even I should have known that.
