Internal resistance calculated by pulsing 0.5A on/off during a full discharge.



Conclusion

There is not much to say about eneloop batteries, they work and they last a long time.



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.

The extra data in this review is not something I will do in other reviews, except maybe a few IR curves may show up.

How is the test done and how to read the charts
