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.

















[size=+3]Conclusion[/size]

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