This is a high capacity AAA NiMH battery.

It looks like shop was out of two-packs and made their own.

They just about live up to the rated capacity and discharge curves look normal for NiMH batteries.

Conclusion

These batteries have high capacity and is also rated with low self discharge, this makes them NiMH batteries.

Thanks for the review.

These seem like a good alternative to Eneloops.

They are not magic!
They have higher capacity than the high capacity eneloops, but it also looks like the low self discharge is worse.
