While this is a classically underrated Samsung cell it has a low current rating combined with only moderate capacity. It is a poor choice for vapers as there are much better cells available with more capacity at the same current rating and/or a much higher current rating.
I only tested this cell because it is being used in some fake Samsung 25R cells. The 22P is easily identified by the four equally spaced radial lines in the venting disk (see photo below). The 25R does not have any radial lines on the venting disk.
NOTE: Other Samsung cells might have these radial lines too.
The 22P’s I tested are from the Malaysia factory (“M” on the right end of the first line of printing on the wrap with “SDIEM” below it). I am rating the 22P(M) cell at 14A and 2100mAh.
The two cells that were tested were purchased by me for that reason.
