This is a high capacity cell that can handle fairly high discharge current.











Very nice discharge curves with good tracking between the cell.
My result is below rated capacity, some of the reason is probably because I terminate charge a bit early (100mA instead of 50mA) and do not discharge to 2.5 volt, only to 2.8 volt.















Conclusion


This cell is designed for higher loads, but it has capacity enough to be a resonable cell at lower loads also.

This is a very good cell.
