I just ran one of these salvaged Samsung ICR18650-28A cells through my West Mountain CBA-II battery analyzer. With a fixed 2A discharge rate, I got 2.33 Ah, 8.26Wh.
I charged the cell on my Efest Luc V4 charger to about 4.2V.
My measurement is right in line with HKJs review , so these cells are still operating at pretty much 100% of their original capacity.
Thank you, Siskiyou, for sharing this deal.
