Samsung is increasing the capacity and this time it is a 4.20V cell, not 4.30V or 4.35V cell. The cell is not for high current usage.










New quality cells, the two cells match nearly perfect. Capacity do vary slightly with load.















Conclusion

The cells are fairly good at keeping high output voltage, even when loaded.
Being Samsung they are very good cells.
