[SIZE=+3]Ansmann AA 2850mAh (Silver)[/SIZE]
Official specifications:
Maximum temperature raise at different discharge currents: 1A:+1,2°C, 2A:+3,8°C, 3A:+6,4°C, 5A:+12,7°C, 7A:+19,0°C, 10A:+24,5°C
High capacity AA batteries from Ansmann.
The discharge curves are normal for AA cells, the capacity is very high.
[SIZE=+3]Conclusion[/SIZE]
These cells are high capacity AA cells, but the price to pay for that is fast self discharge (How fast is rated in the data sheet*).
[SIZE=+3]Notes and links[/SIZE]
*Ansmann has real data sheets for their NiMH batteries.
How is the test done and how to read the charts
