[size=+3]Ansmann AA 2500mAh (Silver)[/size]
Official specifications:
Maximum temperature raise at different discharge currents: 1A:+1,5°C, 2A:+3,5°C, 3A:+6,1°C, 5A:+12,2°C, 7A:+18,2°C, 10A:+26,0°C
AA NiMH from Ansmann with fairly good capacity.
The two cells match, the discharge curves looks normal for NiMH. The capacity also match the rated capacity.
[size=+3]Conclusion[/size]
This looks like good NiMH batteries.
