Want to ask a question to an official Eneloop technician?

1. Will Eneloop ever make a standard sized C, D, or 9V version as their competitor Tenergy does? We’re aware that there are AA conversion adapters for this (size C, D) but the capacity is limited as a result.

2. Has Eneloop considered making a DC solar charger sold as part of a battery package as Costco sells in its AC charger version? IMO it could be a great seller for hikers, preppers, power-out emergencies, etc.

3. Has Eneloop considered making a USB battery charging port version? Competitors are coming out with more and more rechargeable batteries that have this very convenient feature.

I initially read “them” as “eneloop technicians.”

It was a letdown to realize it was probabloopily “eneloop cells.”

{sigh}

Thanks ChibiM. New to charging eneloops and never knew the little AA's could take up to 2A charging.

Would also be interested what the technicians says allowable temps would be for charging AA and AAA for longer life as I could set

my MC3000 to cut off around that and rest the batteries before charging up to full. I always feel they get too hot when charging in some chargers but never knew for sure.

I'm also interested in knowing the answers to questions 1, 4 and 6. :) Especially question 1.

Also, I remember when Power Me Up did that 5000 cycle test on Japanese eneloops, by limiting the maximum charge and discharge levels to prevent most of the wear induced due to charge-discharge cycles.

Eneloops: 5000 cycles and still going...

I would like to know, if possible, the methodology used to test the eneloops for the 2000 cycle claim.

Or, more interestingly, what charge and discharge levels should we not exceed to achieve maximum lifespan?

To put it another way, which causes the majority of the wear and damage from charge/discharge cycles: Charging to full capacity, or discharging to empty (Which in this case means about 0.9 volts when 99% of the charge has been used up, not <0.9 or 0 volt)

  1. They already do.But only available to the Japanese market.
  2. Not sure what kind of solar charger you mean, but they have sold them a long time ago.
    https://eneloop101.com/eneloop-products/ see the solar chargers. if that is what you meant.

  3. You mean that the battery will be extended and that the battery has a charger port on the battery itself?
    I personally think that they will get too long, and wont fit in many devices.

@klrman. At least I got the information that the cut off temperature on eneloop charger(s) is 57 degrees celcius.

@Pablodellama: the cycle life is something they determined following the IEC procedures. More on that in the Advanced charge section on this page: https://eneloop101.com/charge/

Interesting questions.. will write them down.

How can I track down a supplier that will ship Eneloop to South Africa without significant postage charges, are there perhaps any Chinese agents that I can order through and be sure of getting the genuine article?

@ ChibiM…….

1. Ok only available in Japan. Is there any chance for a future test market
in the U.S.?

2. The discontinued N-SC1AS general concept for example looks appealing for reintroduction.

3. A USB AA version primarily for single (or more) cell applications could still fit in lights depending on spring lengths, tension, or tail cap designs. Same for various devices. Granted your comment has valid merit that it wouldn’t fit in a lot of cases. But we’re also maybe assuming that Eneloop can’t compress densities in the original design to compensate for the added length? Maybe they can but haven’t as standard AA dimensions is all they needed to accommodate and built to that standard accordingly.

@zulumoose: I don't think the technician would know. But I would take a look at ru.nkon.nl or a Japanese eBay seller, that sells eneloops with Panasonic text on the side instead of eneloop.

@nottawhackjob: 1. Not sure if he can answer, but good question. 2. Fair point.. would like to know as well. 3. I think most of those ones probably have an AAA battery inside. so the size difference is not as big. like this: http://www.oempowerbank.com/news/japan-customer-order-10k-rechargeable-battery-8753042.html or https://images-eu.ssl-images-amazon.com/images/I/513EM%2ByurXL._SL500_AC_SS350_.jpg

Will write that down as well. thanks for all the questions!

@ChibiM……

3. My fault sorry should’ve been clearer. This is what I have in mind.

I propose this as I’m not keen on charging ports on flashlights in particular. I think they’re just an eventual invitation for moisture and charge port grommet failures especially if an EDC.

Thanks ChibiM, that gives me a benchmark now. I may set my charger to cut at 50C and after a rest charge back to full.

Ask him about Japanese girls .

Can we expect more interesting colors and collectors editions ?
Any new tech on the horizon?

“Ask him about Japanese girls .”

You’ve been lookin’ at too many battery tubes and tail caps me thinks.

:open_mouth:

@nottawhackjob: gotcha. That's the type I was thinking about as well...

@klrman: good idea.

@boaz: "Ask him about Japanese girls" what would you like to know? How tall they are?

What is planned for the next generations of NiMH batteries, if any? Are we pretty much maxed out on that chemistry?

Definitely one of the questions on top of the list.

@boaz: ”Ask him about Japanese girls” what would you like to know? How tall they are? ”

Don’t encourage him. IOW there’s maybe a subliminal reason his avatar is shaped and colored that way? I stand corrected AFAIK it’s some sort of esoteric retro-lamp so disregard.

:open_mouth:

I know Boaz pretty well, he wouldn't do that!

“I know Boaz pretty well, he wouldn’t do that!”

Ok. I feel better now. I apologize. My mind was in the gutter again. From now on…… :innocent:

But he does ask perhaps a good albeit nebulous question. Their general condition could be important to the flashlight community in some way. I’m not exactly sure how but if he asks it there must be a sound rational scientific lumen-related technological reason behind it we don’t yet fathom. Eneloops, Japanese girls, discharge curves, etc., the complex interrelationships could be profound.

:beer: :student:

Lol

Can Eneloops be used to power robots that look like Japanese girls?

Just asking… for a friend, of course.
