I do not know the brand of this 2635 battery, this size is rather uncommon (It is about half the length of the more common 26650).
Discharge curves looks fairly good and the battery has constant capacity up to about 7A.
Conclusion
A uncommon size, but if you need this size the battery is fairly good (The performance cannot match the larger 26650 cells)!
