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?

You are a flashaholic if you are forced to come out of the closet, to make room for more flashlights.

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.
