Test/Review of Fujitsu AA HR-3UTC 1900mAh (White)

Fujitsu AA HR-3UTC 1900mAh (White)



Official specifications:

  • Nominal voltage: 1.2V
  • Typical capacity: 2000mAh
  • Minimum capacity: 1900mAh
  • Low self discharge (LSD)
  • Retains 85% charge after one year, 70% after 5 years.
  • Rechargeable up to 2100 times.




Maximum temperature raise at different discharge currents: 1A:+1,3°C, 2A:+3,5°C, 3A:+5,9°C, 5A:+10,5°C, 7A:+15,3°C, 10A:+20,6°C
This is the long life version of the FDK AA batteries.











This battery has a very good performance, but I suspect it has been in storage for some time because the first cycle has less capacity than the second cycle.















Conclusion

They are very good batteries, but you trade a bit capacity for the very low self discharge.
