[size=+3]Samsung ICR18650-22F 2200mAh (Green)[/size]
Official specifications:
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.
[size=+3]Conclusion[/size]
Not the most interesting battery today, but the cell is good enough within its limited capabilities and it can easily surpass some cheap brands.
[size=+3]Notes and links[/size]
How is the test done and how to read the charts
