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?

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)?

1. Is 1A charging ok with AA Eneloops
2. What would be the best settings  Panasonic could recommend for charging AA and AAA with a MC3000?

-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)?

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!

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

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. 

Please check out this page: https://eneloop101.com/batteries/rewrapped-batteries/ 

Add Fujitsu to the list.

Good question. I want the answer….. XP

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}

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)

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)

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.

@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.

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

 

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 .
