A NiMH with record capacity from a cheap brand, that is not realistic.
Discharge curves tracks in an acceptable way for NiMH and looks acceptable for the capacity. The problems is that the capacity is only 1500mAh, not the stated 3800mAh or in the 2000-2700mAh range that is very common, but less.
This is not a high capacity cell as marked, but a low capacity cell.
