Ansmann AAA 800mAh 5035042 (Silver)







Official specifications:

  • Nominal voltage: 1.2V

  • Maximum charge voltage: 1.5V

  • Nominal capacity: 800mAh

  • Maximum continuous discharge: 2400mA

  • Fast charge: 800mA

  • Recommended charge termination: -DV/DT: 0…5mV, Temp rise: 0.8…1°C/minute

  • Internal impedance: <40mOhm @ 1kHz

  • Low self discharge: >80% after 12 months.




Maximum temperature raise at different discharge currents: 1A:+2,3°C, 2A:+5,7°C, 3A:+8,6°C, 5A:+12,8°C
Ansmann have two 800mA AAA cells, one is marked for phone usage, this is the other.











The two cells I tested do not match perfectly.
















Conclusion

It is fairly good 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! It looks like these perform slightly better than the phone ones. Do you think it has to do with the age of the cell/variation in quality or do you think it’s a different cell?
