Amazon Basic AA 1900mAh (White)



Official specifications:

  • Typical capacity: 2000mAh
  • Minimum capacity 1900 mAh
  • Nominal voltage: 1.2V
  • Low self discharge (LSD), 80% capacity after one year, 70% after 3 years




Maximum temperature raise at different discharge currents: 1A:+1,5°C, 2A:+3,8°C, 3A:+6,6°C, 5A:+12,4°C, 7A:+18,2°C, 10A:+23,6°C
Amazon has two types of NiMH cells with about 2000mA. The whites are rated for 3 years LSD (The black only 1 year). They are manufactured in Japan, the black in China.











The discharge curves looks fine, but the capacity is not that high (Common for long life LSD cells).















Conclusion

The cells has very good performance. The capacity is slightly less than the Amazon black 2000mAh, but it has a promise of better LSD ability.

Thanks for the review HKJ. Looks like it isn’t quite identical to the eneloop, but still a good cell.

Has very similar performance to third-generation Eneloop at 2A
