I have found this cells too, red wrap, red ring.
I got them (9 cells, 3x3 evidently) from an old Toshiba notebook. Regret I have not kept the outer label of the battery pack.
They too have the "F" engraved at the bottom. Also, there are very light stamping on the cells: HBOFJH3 (the same on all cells) and then a six-digit coded lot/date/... (e.g. 066089, 066121, 054468,...).
The Green one are from a chinesse unkown brand FP 18650, but looks it has the rated capacity, tested with my modded opus.
these was also harvested from some counterfeit batteries that also has a fake rated capacity in their label. Also the text looks self explanatory, it shows the production date and the capacity.
