A standard 2600mAh cell from Samsung.










Very nice matching of the two batteries and capacity is nearly independent of load.















Conclusion

This is a very good cell for a standard 2600mAh cell.
Remember that the cell is unprotected this means it will have higher voltage at "high" load than protected batteries.
