    "Never install, carry or handle". OK but what are they for then?

    These are cells that are meant to be assembled into larger battery packs by electronics manufacturers, like laptop batteries or e bike batteries.

    The cells are fantastic for flashlights, lasers, and vapes, but Samsung does not sell them to end consumers and wishes other companies would not do that either but fuck Samsung I'm not stupid.

    I am stupid. How dangerous would one of these be to me if I picked it up by the ends (Or whatever to make it discharge into my body)?

    It wouldn't be dangerous at all to do that. They can be dangerous because the cells are unprotected, so if you short the ends together with something a lot more conductive than your fingers (eg metal) the cell will very quickly overheat and possibly catch fire, since there's no protection circuit to detect and cut off current when a short is detected.

    I remember in high school, one of my teachers showed the class a battery and said "This is the same battery they use in vapes. The big ones... not the small ones you guys use"
