What would you like to ask an official eneloop technician?
I'm scheduled on having a meeting with one of them next month, and if there are any questions you would like to have answered.. please let me know! (if its not answered already on my website).\
please post them here
What kind of technician are we talking about? Something like a chemistry person who tinkers with the actual science of the cell itself?
Any reason not to use them in my game cameras?
I honestly don't know who he is, and what he does. But the host of this meeting is at least the person who helped developing eneloop back in 2005.

Hi Wiley, I will ask him: Are there any reasons not to use eneloops in WIleys game camera?
The Eneloop 2005-2018 info thread
Are the Ikea’s Ladda batteries, Eneloops? If yes, what generation? The 3rd?
Thanks!
1. Are there any real internal differences between the various “generations”, or has the technology been basically the same since 2006 with just more accurate manufacturing techniques or quality control? If it’s basically the same, then are the increases in stated cycle counts mainly due to discovering they had better performance than originally thought, or has manufacturing really doubled the performance with respect to cycles?
2. Does trickle charging really damage Eneloops?
3. Are other LSD brands such as Duracell and Ikea Ladda really re-badged Eneloos? If so, what generation?
4. What is the best way to store Eneloops for extremely long shelf-life (i.e., when not used in devices)? What charge level?
5. I have noticed that heat is about the only thing that really destroys the capacity of Eneloops. Hot, but lower than heat typically generated in lithium-ion lights. What is the maximum temperature recommended during discharge?
6. I have 2006 AA Eneloops that still have most of their capacity, even at reasonably high discharge (2 amps). Their internal resistance is higher than new cells, but still pretty good. What is the expected life-span of Eneloops, if cycle counts are not a factor (i.e., less than 100 cycles)?
-What is the relation between deep discharging (< 0.9 Volt) versus cycle life and internal resistance?
- Is it true that discharging an Eneloop Pro down to or below 0.9 Volt reduces cycle life with about 100 discharge cycles?
- How prone are Eneloops to internal cell damage because of physical shock and vibration (for example dropping them on a concrete floor from a height)?
- What is the fastest way to kill an Eneloop (so we know what not to do)?
I could also ask, are the Toshiba, Canon, Nikon, Watson, Ikea, Amazon batteries eneloops?
At least somebody had to drop the IKeabomb in the thead.... literally EVERY eneloop thread somebody has to drop that in there..LOL.

Good questions. Don't know if I can ask the ikea question though.....
The max temperature for charge is about 60degrees celcius. But eneloop chargers (maybe not all) will cut the charge at 57 degrees, cool down and continue charging.
The Eneloop 2005-2018 info thread
1. ecommended is .5C-1C for eneloops. So 1000mA for AA to 2000mA
2. I will ask for the best setting.. like -dv/ time,voltage etc... (probably more interesting for refresh cycles)

On a side note… I use them (Eneloops) in all my cameras (game & any that take AA’s) & have for years. I get great results with them (Eneloops)….
In fact Eneloops are the best thing since sliced bread!!!

I have some well over 10 years old that are still going strong. So far… knock on wood…. I have never had one go bad.

I have to think about this one ChibiM. But this must be exciting meeting this person or not? Sounds really cool to me!
@ Teacher: I will ask the following question: Are there any reasons not to use eneloops in WIleys or Teachers' game camera?
@ hIKARInoob: Yes.. it is. Especially since I don't know who is actually coming. That keeps it interesting

Thank you… wiley07 & I will look forward to the official answer.

But I will try to ask between nose and lips
The Eneloop 2005-2018 info thread
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.
“In many things in order to truly understand the small picture you have to understand the big picture first.”
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)
@nottawhackjob
https://eneloop101.com/eneloop-products/ see the solar chargers. if that is what you meant.
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.
The Eneloop 2005-2018 info thread
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?
Beam me up!
@ 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.
“In many things in order to truly understand the small picture you have to understand the big picture first.”
@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.
http://budgetlightforum.com/node/47663
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.
“In many things in order to truly understand the small picture you have to understand the big picture first.”
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?καὶ τὸ φῶς ἐν τῇ σκοτίᾳ φαίνει καὶ ἡ σκοτία αὐτὸ οὐ κατέλαβεν
