Does Amazon relabel eneloops?
Made in Japan
Modellnummer: HR-3UTG-AMZN (8P)
70% after 3 years remaining.
Similiar look, capacity and discharge values…
Only big difference they are rated for 1000 cycles…
Is there any definitive answer on how charging current affects cycles over the lifetime for the eneloop and eneloop pro? I generally charge all my AA at 700ma and my AAA at 500ma. Would it be better to charge faster or slower?
I`m confident that won`t effect the cells in any measurable manner.
I havent seen any hard evidence with somebody actually doing those tests.. those would be very very time consuming.
In the very very long run you might see a difference, only if you keep track of every little detail.
So the currents you are currently using are good enough!
the Panasonic chargers usually charge AA with 550mA and AAA with 275mA.
conclusion: No, there are not enough tests that would show the difference between charging AA eneloops at 1A or 750mA.
although member "powermeup" at CPF has done some extreme testing on eneloops that has some interesting results. but that kind of testing is not comparable to real life usage.
old vs new
Left: Made in Japan 3rd generation Right: Made in (Japan?) 4th generation
I think they now make 2 versions, 1 in China (bottom) and 1 in Japan... (right)
Both say 70% after 5 years.
but this one below, is definitely made in China
65% and from a Chinese website
Backside of this 65% one, showing that its made in China
Oh ChibiM look, you are now famous person 
better start stacking those eneloops because demand will sky rocket now 
Oh so Julian is a member or a lurker? Julian come forward I’m a fan.
Thanks for the link! Interesting guy!! Lots of useful info in his videos.
Hey ChibiM, no new models from Panasonic (I hoped they will have something new for mid 2015) or you just stopped updating this thread?
I've been visiting their website regularly in the past few months, but they haven't added anything new.
I really thought they would have a special eneloop 10th anniversary edition, but nothing. The latest edition is just a 2bay charger for eneloop lites,no new batteries.
Hmm, kinda disappointing, 10th anniversary i nice round number, should be celebrated accordingly 
The 10th Anniversary of Eneloop is later this year. November 2005 was the launch month of the original HR-3UTG series. I’ve been reliably informed that Panasonic will be doing global 10th Anniversary promotions for eneloop. Kind of ironic since Panasonic dont dont own the technology or the factory eneloop is made in (except the Chinese made eneloop that are actually using Panasonic Evolta technology, not Twicell factory technology the Japan made cells have always used).

Panasonic announced recently Eneloops can now hold a charge of 70% for up to 10 years. http://shop.panasonic.com/about-us-latest-news-press-releases/05132015-eneloop-rechargeable-batteries.html
Packaging has already been updated to state this and we should see this slowly trickle to US retailers over the next few months. Panasonic Japan’s website still does not show this “increase”.

Product numbers of the actual cells have not been changed as far as I could tell.
Is this far fetched? Maybe.
Could this be a prelude to a “5th generation”? Who knows!
accumulator mentioned a couple of weeks ago, that he had found an unopened package for 1st generation AA eneloops with an April 2006 date code. His findings of the two cells from the package showed 72% and 73%
I also recently got a pair of 1st generation AA eneloops with a February 2008 date code. It came with the NC-MQH03 charger set from Singapore. I don’t have the fancy ZTS battery tester yet nor do I have the good Maha or La Crosse chargers to check this accurately yet. But, my cheapie Delkin tester showed 3 out of 5 lights. Not bad at all! I’ve decided not to touch them yet and will wait to test these for real on my friend’s La Crosse BC-1000 charger to get definitive results.
Still the same cells, but updated numbers, probably after testing 10 year old cells ;)
Codes are still same.
So, no, they aren't the 5th generation. If you look at it, the Chinese envelops are the fifth generation...
And by the way, special anniversary editions have usually come to the market before the anniversary rather than after! (Disney)
Still looking forward to some new stuff, but I will probably not be in Japan anymore by then.
With Panasonic's ownership of the Eneloop brand, they've been doing some weird things to it over the past couple of years... who knows what will happen later this year?
I can't believe I missed Uniqlo's Eneloop t-shirts a couple of years ago! 
yeah, a friend of mine has one! he got one from a "lucky bag".
and it was one of the few shirts that were actually his size ;)
Im not such a eneloopy fan though.. maybe I should just get one, just to say I have one.
this link might interest you as well.. a lot of eneloop stuff ;)
I just happen to like many out of the ordinary things, and a Eneloop or Kewpie (missed that one too) t-shirt counts
I’ve seen that thread before. It’s very informative, but there are actually some slightly newer versions of some of those Eneloop universe products 
I am just emerging from a dark age, having purchased my first high-power LED flashlight last month. It runs on 18650 batteries, but since the charger I bought, a Nitecore D4, can charge NiMh in addition to Li-ion, I decided to buy some Eneloop Pros. I selected the Pro, because I want the longer runtimes it offers in AA flashlights. I have 16 AAs and 4 AAAs arriving next week.
Since placing my order, I have learned that capacity and number of cycles are not the only differences between regular and Pro batteries. The Pro model is also better for devices that draw high current.
That's fine. My reason for posting, however, is this. The same post where I read about high-current draw said that regular Eneloops are better in low-current applications. I understand that they may be more cost-effective, but are they really better? Is there any reason I should not run my TV remote on Eneloop Pros? What about the AA flashlights I anticipate buying? Frankly, those will also be run on low-output settings most of the time.
From what I read, using high(er) capacity cells in low draw devices is bad because the cells sit mostly unused and internal resistance eventually increases until you go through a “refresh” cycle on a good charger. Not only that, using high(er) capacity cells in a low draw device is counter productive… they will self discharge before you even used up the cells. In other words, it’s not worth the cost!
For remotes and clocks, I’ve ended up getting a bunch of Eneloop Lites as they’re better suited for these applications. They are low capacity cells meant for low draw devices. Nevermind the fact that they have way more number of cycles than any one can practically use lol… At the very least, I feel it’s better to use regular Eneloops instead, which is what I’m using now in my DVR remote because that thing takes AAAs and sucks down batteries like none other
Other than high power flash lights, something that is better suited for Eneloop Pros are things such as camera flashes, hand warmers, cell phone battery booster packs, and electric shavers
Thanks, Kouryu, for a great explanation!
Not sure just what I should do now. I am the proud owner of 20 Eneloop Pros, but most of my AA needs are for low-draw devices. I can either buy some regular Eneloops or Eneloop Lites or else abuse the Pros I now have...
Guess I'll just have to buy a few AA flashlights like the ThruNite TN4A (NW)! More likely, I will buy some lights that use 1 or 2 AAs. For applications where the TN4A might be useful, I am inclined towards Li-ion solutions.
Kouryu has got it pretty much correct. Ostensibly it’s a waste of a good high capacity using the high capacity, high current cells for low drain applications such as TV remotes. They’ll work fine but the longer cycle life 2000mAh white cells will do a better job over the years & even better if you can find them are the high cycle life ‘Lite’ cells. These are half the capacity of the standard white cells but capacity is not important in low drain use as you’re almost never going to use anywhere near the whole charge anyway. Cycle life plus of course the low self discharge characteristic is the key factor for these cells.The lite batteries are designed for low drain long life use being rated at 5000 full cycles. They’re also made to handle continuous charge so appliances that sit on a low rate charge all the time when not in use such as shavers, cordless toothbrushes and solar charged garden lights are perfectly matched to the ‘lite’ batteries. Just like the the other two models the Lite cells are manufactured at the FDK Twicell factory in Japan so whether you buy Eneloop Lite model BK-3LCC (formerly HR-3UQ) or Fujitsu Lite model HR-3UTLA you are buying the same battery.
