    What are the Eneloop Lite design for? Are they good in low drain devices?

    I seen them advertised on Amazon by a second party. I think there probably from China they said made in Japan.

    Help out is an understatement! Between the thread starter and your web page it like getting a PhD in Eneloop...simply amazing, I cannot thank you enough.

    It`s hard to say. If they are older stock from Japan (2013-2016) they are made in Japan. If newer stock than made in China. You should probably check with the seller.

    Awesome thread, thanks for all the information. Love my eneloops, mostly in household items.

    @ChibiM , I couldn't find on your website the information how Panasonic does the testing of Eneloops to achieve the 1800-2100x cycle rating.

    Question (FAQ ;-) :
    How does Panasonic cycle the Eneloops in tests to achieve the advertised 1800-2100 cycle number rating? Do you know the testing conditions and parameters? And what is the technical criterion to call the end of the test?

    The retail packages cite §7.5.1.3 afaik of IEC , but only few people know what's it saying. Maybe you could write out the full testing conditions\parameters or summarize them in a nutshell🐁. Or do you think that it is not interesting to know how Panasonic tests their own batteries?

    For example do they use 1000mA charge rate and -500mA discharge rate for the cycling and 0.90V as cut-off? (These are the default values MH-C9000 and CPF users use)

    Hey Kreisl,
    Interesting question. Well, I do know (partly) how they test them (Thanks to member Viking here on CPF), so I could probably summarize that on my site somewhere. I might have to put that in the FAQ or in the Charge section. The thing is though that even with the IEC and JIS documents I watched I still have unanswered questions myself So if people ask me questions about the details I might not be able to answer them satisfactory.

    At least I can say for now that the test will be stopped when the remaining capacity it 60% of the original capacity (at least that is what I already have written somewhere on my site). And no, the testing parameters are not 1000mA charge and 500mA discharge parameters for the cycling rating. When I have time to dive into that again, I hope I will be able to make a summary that is somewhat understandable .
    Maybe that Mark over at Ultrasmartcharger.com already wrote about the these parameters.... somewhere

    Thanks for your consideration.
    I don't have JIS , just IEC . And it's effing complicated, can't wrap my nuts around it. But maybe you can manage!!

    Check out Eneloops: 5000 cycles and still going... thread for some answers.
    Poking around Mark's UltraSmartCharger forum should provide some additional information.
