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

Do you test nimh right out of the box? They say using them a few times increases capacity.

Henrik, thank you for performing this test. Thorough as ever.

Question; isn’t this the good-old Eneloop Pro (bought them in 2011) with another wrapper?
Or do you think (or know) that this is more of a fine-tuned version of that golden oldie?

I would expect them to be the same as the current generation Eneloop Pro

Thanks for the review. Your measured capacity aligns with what I saw on my cells purchased from Newegg at the beginning of this year, tested with my Opus C2400.

Thanks HKJ!

Thanks for the review, these look really nice.
