Description :
Sony US18650GR 3.79V (as received) 93mOhm, This Sony cell is a bit of a departure for me – IMR cells aside – as it is obviously a bare laptop cell, or possibly for power tool use, and has not been converted in any way for use in lights. So no protection circuit, no button, no aftermarket wrapping, and the stock wrap does not extend to the bottom of the cell. It is common for cells that are intended for use in packs to have an entirely bare base in order to make welding/soldering the cells together easier to do.
