Internal resistance measured by pulsing 0.5A on/off.
Conclusion
These cells are some of the highest capacity AAA cells, but because these cells are not low self discharge they are best used for equipment that uses some power and is used frequently.
Notes and links
How is the test done and how to read the charts
Compare to other AA/AAA batteries: Alkaline/NiMH/Lithium

Thank you for checking these out.

One of the main problems I’ve found with this kind of very high capacity NiMh (AA/AAA) is the internal resistance goes way up in short order, capacity goes down, and self-discharge becomes a problem. Simply won’t buy this type of cell anymore.

I cycle one time, then I start from the lowest current.
