Very nice tracking between the cells, they must be made by a very good manufacturer.

Thank you. I’ve been curious about these cells vs. Eneloops.

I’ve had a few of these HKJ and i found that they need breaking in with afew everyday use discharges to get the full ah rating. They may have changed manufacturer but if their anything like the ones i got last year and gave my daughters they’ll get better with abit of use.
Thanks for posting, it’s always good to see a graph.

The real question is the self discharge rate.
BTW, you should at least mention the fact that these cells are LSD type.
Thanks HKJ! Smile

My English isn’t perfect but I’m trying to improve it. If you see something that doesn’t sound right or is just plain wrong, please feel free to point it out! Smile

Great info.  Thank you HKJ.  I have some of these or maybe one generation back, if there is one.  They work great and reach the same current levels as the LSD Eneloops in my lights.  They are slightly wider in diameter and don't fit some lights though.  Only specific example I can think of right now it this light.
