Curves looks like NiMH usual do. The cells are a bit lower than rated capacity (2700mAh often is that). Output voltage is slightly lower than the best batteries.

Thank you for completing the review on this battery.

Could you please add another battery to the review queue?

I came across this:
https://www.aliexpress.com/store/product/LEISE-1-2V-AA-2500mAh-Ni-MH-Bat...

I had capacity test with the same Miboxer C2-4000 charger of this battery, and capacity came out higher than this 2700mAh labeled – had values exactly matching (within 2%) the stated value, and had also lower internal resistance, than the 2700mAh labeled battery.

Thank you for another useful review.
The major problem I’ve had with high capacity cells like this is they are relatively short lived. Capacity goes down and IR goes up in a short time. After awhile they are often worse than a stock Eneloop.
