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
