Official specifications:
/Samsung%20ICR18650-22F%202200mAh%20(Green)-info.png)
The datasheet for this cell says 2008, i.e. it is a old design, this can also be seen on the limited capacity and current capabilities.

The discharge curves looks good enough, good tracking between the cell when not overloaded.

Conclusion
Not the most interesting battery today, but the cell is good enough within its limited capabilities and it can easily surpass some cheap brands.

Thanks for the test. If these are cheap, they have their purpose I guess.

I dont understand – do these come with protection circuit or not?
How do they cut off at 2.75V?
What are they good for, aside from lower capacity?
Mine dont set any records but for my C8/S7 lights they work just fine.

No protection board and you must control the cut-off.
Today they are old cells and not very interesting.

I see, thanks, folks!
Ive noticed that Gearbest have them for 2.85$ per cell, so wanted to know whether I should buy a couple for lights:

So I bought them back then and now pulled out of storage to charge and use in light for the first time :D!
Nothing to report, 3.6v after years of storage, not bad, huh?
Do you remember at what voltage your cells were stored? That is a meaningful detail to determine the overall outcome. If you stored the cells fully charged, bad start.
You can use an analyzing charger to see how they're doing capacity wise.

Please avoid fully quoting lenghty posts, namely with nested quotes. Trim quotes down to the essential. Helps with neatness and legibility. Thanks.
- Yeah, but is it ultra high CRI?
To be honest, I dont remember, but you can check out my experience with Pananocis 3400mAhs, no scientific data:
After storing some of my Pana’s protected 3400 ICR’s(green ones) for a year fully charged, not properly “cycled” and rarely used before being put into storage and/or after being taken out from storage showed 3000-3100mAh capacity with Lii-500 charger.

Will see how well these green Samsungs hold up after couple of cycles as my bicycle light batteries on S2+.
