Test/review of Sofirn AAA 900mAh (Black-Blue)

Sofirn AAA 900mAh (Black-Blue)







Official specifications:

  • Capacity: 900mAh

  • Voltage: 1.2V

  • Chemistry: Ni-MH

  • Rechargeable: Yes

  • PCB Protected Board: No




Maximum temperature raise at different discharge currents: 1A:+2,2°C, 2A:+5,4°C, 3A:+8,4°C, 5A:+12,3°C
In my test Sofirn AAA batteries this is the lowest capacity cells (The other are 1100mAh and 1800mAh), can this battery live up to its specifications?











The discharge curves looks fine with a very good match between the cells and capacity is close to 900mAh.















Conclusion

These cells has about the same capacity as the 1100mAh & 1800mAh and that is about 900mAh.
The discharge curves looks fine.

Compare to other AA/AAA batteries: Alkaline/NiMH/Lithium

LOL! So they are all basically the same cells inside, just different labels and price points. :person_facepalming:

Thanks for the review, HKJ.

Not too bad, really. This product is obviously geared for the knowledgeable people, and it is a good product. The cells labeled 1100 and 1800 are for the crowds of foolish and philistines, still being good cells if mislabeled. Can't say the same with certain other brands…

Cheers
