ICR18650-24E Samsung SDI 6A2 recovered from a laptop battery pack.
Are these usable, and how should they be charged ?

Depends on their condition. If they have been overdischarged they are almost certainly dead; if they are charged but very old, they can be charged slowly and used in low-power appliances, but you shouldn't use them in a flashlight.ICR18650-24E Samsung SDI 6A2 recovered from a laptop battery pack.

There is always protection circuitry, but it works on the whole pack. The single cells, once harvested, are unprotected.I've got a laptop battery that I suspect has 18650's in it as well, my only question is, are these protected at all or no? What kind of extra care would I need to take if I wanted to harvest them for flashlight use?
