-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)?
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.
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)
I think not, but I’ll be interested in hearing his answer also. :+1:
On a side note… I use them (Eneloops) in all my cameras & 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. 
. . :+1:
I have to think about this one ChibiM. But this must be exciting meeting this person or not? Sounds really cool to me! :partying_face:
@ 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. :+1: .
Add Fujitsu to the list.
Good question. I want the answer…… XP
Check the page, its already on there :p
But I will try to ask between nose and lips
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)
@nottawhackjob
@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!
