Test/Review of Camelion AA Premium 2300mAh (White)

Camelion AA Premium 2300mAh (White)







Official specifications:

  • Capacity typical: 2300mAh

  • Capacity minimum: 2200mAh

  • Nominal Voltage: 1,2V

  • Dimensions (Ø x L mm): 14,1 x 50,5

  • Weight (g): 29,0

  • Electrochemical System: Nickel-Metal Hydrid

  • Low self discharge: 90% after 6 months, 85% after 1 year.



Maximum temperature raise at different discharge currents: 1A:+1,4°C, 2A:+3,4°C, 3A:+5,9°C, 5A:+11,5°C, 7A:+17,2°C, 10A:+24,5°C
Camelions medium capacity and LSD (Low Self Discharge) NiMH batteries.











The discharge curves looks good with just about perfect tracking between the cells and some performance at high current.















Conclusion

The cells has good current performance, but capacity is a bit low. The LSD performance is not in top for medium capacity cells.



Notes and links

How is the test done and how to read the charts
Compare to other AA/AAA batteries: Alkaline/NiMH/Lithium

Any idea why the 100mA discharge curve is so low?
Very first cycle?
If so, it might be a good idea to do 1 or 2 full cycles before the actual test starts.

Yes, it is because the battery has been unused for some time, doing a cycle before I started the test would have fixed it.
I have done all my tests that way, I am not sure it is a good idea to change now.

:confused:
The four point test setup could have been a good time to switch though.

Yes, but that was only for LiIon, not for NiMH.
I may change for NiMH at a later time, but it can be a bit more difficult to handle voltage drops.
