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.


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

Notes and links

How is the test done and how to read the charts

Compare to other AA/AAA batteries: Alkaline/NiMH/Lithium

Thanks HKJ!

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.
