A standard 2600mAh cell from Samsung.










Very nice matching of the two batteries and capacity is nearly independent of load. This battery has slightly higher capacity than the 26F model, but lower voltage.















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.
