There is significant difference between the two batteries and the capacity is 2000 and 2200mAh at low current. The batteries can handle up to about 7A.

Conclusion

These cells where never going to be anywhere near the rated capacity, instead they have less capacity than most other 26650 cells.

I will call them bad cells.
