Pulsing 1A on/off makes it possible to calculate the internal resistance during discharge. H means current on, L means current off, measurements are done just after switching the current.
Conclusion
The batteries looks like very good quality, but the capacity is low. They are rated for more cycles than regular eneloop.
Notes and links
How is the test done and how to read the charts
Compare to other AA/AAA batteries: Alkaline/NiMH/Lithium

Wow! Thanks for quick response to my request. If I ever wear one of mine out I’ll let you know.

Thanks for the review.

Interestingly, there appear to be several versions of this cell, depending on the market. The ones sold in Japan are actually now made in China, and they are rated at 5,000 cycles. On my Opus C2400 charger, using 0.2A discharge rate, they showed capacity of 628 mAh.

I’ve been using them in my cordless phone for the past 2 years or so.

I’ve got some AA lites on order. Guess I like the robin egg blue color. Could you test those too?
