The discharge curves looks normal for NiMH AAA cells and capacity is also about average.

The batteries are way below rated capacity, but their actual capacity is fairly good.

Funny how the claimed capacity, as was mentioned in the review, is ridiculous.. but if they'd put the actual capacity on the label it would have been no big deal since their in line with other top quality AAA NiMH batteries!
