Fujitsu AA HR-3UTHC 2450mAh (Black) 2019



Official specifications:

• Voltage: 1.2V
• Energy: 3Wh
• Nominal capacity: 2.45Ah
• Typical capacity: 2.55Ah
• Weight: 30g
• Cycle life: 500 cycles.
• Low self discharge: 85% after 1 year

Maximum temperature raise at different discharge currents: 1A:+1,0°C, 2A:+3,0°C, 3A:+5,2°C, 5A:+10,5°C, 7A:+15,8°C, 10A:+21,6°C,
This is a retest, I have tested these batteries before.











The two cells tracks nicely and capacity looks good.















Here I pulse a 1A current to measure internal resistance during discharge.



Conclusion

This looks like good quality NiMH batteries.



Notes and links

I am replacing my NiMH charger test batteries, they are from 2016 and some of them has a fairly high internal resistance. Some of the bad chargers I have tested have probably increased the deterioration rate of them. These will replace the EneloopPro, but I except to still use a EneloopPro as a example of an old cell.

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