Overview: All Eneloop batteries 2005-2024

Eneloop XX are sold with different numbers in different countries.. which might cause confusion....at least it confused me.

These are all HR-3UWXB, 2nd generation XX/PRO but with different pacakges.. 1 with nominal mAh rating, others with minimal mAh rating.

Above left is the Chinese version, and right is the English version

and below is the Japanese version:

Thanks for compiling this list!

I didn't know there is a 3rd generation already.

I think it would look better in a table... but as it is - great to have this info all in one place!

WOW! Thanks! Great job!

Nice job. Thanks for your hard work.

I like the idea of having a whole set of eneloops that are different color or have different lables.

very nice job ty

from wikipedia...

eneloop plus

eneloop plus have a PTC thermistor built-in that cuts the power when the batteries are overheating. This makes them especially suitable for toys. Other specifications are identical to the second-generation eneloops. The product number is HR-3UPT (AA) and the battery was released in Japan in December 2011

is about that

Eneloop PLUS:
HR-3UPT: AA (70%Claimed capacity after *35 years, date November 2011


...tables are WAY better!!!

/trolling mode off xD

Thanks so much ChibiM. I want to purchase some Eneloops and this helps sort out the confusion over which ones to buy.

Thanks very much for the data. Do you have the same for Duraloops ?

Hi,

sorry, there are not many duraloops around here!

If someone could provide the info, I could probably add it to the list...

I almost got a headache of checking both English and Japanese websites to get all the info.

Thanks,

I will add more info to the Eneloop PLUS soon.(dates could differ, especially looking at the release date, manufacturing date, news date, release date in Japan or overseas etc.)

Also, Wikipedia is WRONG! these are not the same as the 2nd generation! they are the same as the 3rd generation. 1800 cycles, 70% after 5 years storage.
Thats my info from the Japanese Eneloop website.

Also, I will make a table to include on the bottom of the list, as soon as I can

Panasonic seems to have very good cells under their roof! Eneloops and 18650 3100mAh NCR batteries..

I guess they are having the best engineers from the 2 groups together! Hopefully they can get their heads together, and improve both types of batteries even more

GREAT WRITE UP!

Thank you very much...!

Here a tiny bit of info for total newbies:

Another term for "Rated capacity" is the word "Nominal capacity", and i prefer the latter in RL although < rated capacity eneloop > is more popular with google.

And there is the "Minimal capacity". For a standard Eneloop AA, the minimal capacity is 1900mAh and its rated at 2000mAh, so the nominal capacity is 2000mAh.

When you have a charger with a digital display (BC-700 clone, Imax B6 clone, C9000, ..) and are asked to punch in the "Please set battery capacity: ...", then you always enter the nominal capacity ("2000") and never the minimal capacity ("1900").

This is interesting/important to know because when you look at the Eneloops itself, all you can read is "1900" on the physical cells. So the uninitiated will be tempted to run his/her BC-700 set to "1900" instead of "2000".

Uhmm Dinoboy? can you read private messages? ;)

(Im just talking about this same thing via PM with Kreisler)

As far as I know the little ® was part of their re-design back in 2007.
But it seems that the same symbol is missing on some eneloops in Europe.. at least the ones that Kreisler has.

As far as I understand, the symbol is present on all eneloops sold in Japan.

yeah dinoboy, good point made!

I was thinking that maybe the retail packages are filled with ®-symbol'ed cells because my white ones are original bulk cells bought from ebay, provided by various German sellers with direct bulk supply from Sanyo Europe.

But then i look at my glitter cells, and there is no ®-symbol either. (Glitter are always sold in retail packages, and i got mine in original German language packaging (bi-lingual), 8-pack.)

So the symbol has nothing to do with retail vs. bulk.

I would assume that the machinist who operated the printer had one nihonshu too much the weekend before :beer:

S)

I think its interesting to mention, that I just found a Japanese website with different tests on eneloops,
and the 1st generation eneloops still hold 80% after 3 years! amazing!

So everyone that has still the 1st generation eneloops, dont worry, dont hurry.. yours are doing still perfectly fine
you dont need to get the newest and latest .....yet

(But I still want to get a set of the newest versions, anyhow)

That's right. Sometimes you gotta undersell yourself a little bit so you can leave enough for the next marketing push. If the 2nd generation was actually rated at 1650 but they could still only squeeze ~1800 out of the 3rd generation then you don't have as much separation to make it an effective selling point. Just food for thought

The increased number of charge cycles is not a marketing trick, it is achieved by making the cells more robust. It's detailed in the brochure announcing the release of the 1500 cycle cells. So it's good for consumers either way.

Great job, ChibiM! I didn't even realize they had improved the Eneloops again.

I bet there are some lab techs who just charge, discharge, and recharge Eneloops all the time. It took them a long time to get to 1,000. Then when they got 1,500 they started printing that on the packaging. Now they have finally gotten to 1,800 cycles, so they have changed the packaging again. It's just the same batteries! (just kidding, kind of)

I find it funny that people are collecting batteries because they look pretty. I must say I'm tempted too though, haha.

Here my own measurements of exact weight (measured with precision scale and with kitchen scale) and effective capacity (measured with C9000):

Eneloop AA Glitter (HR-3UTGA-8BP GLITTER):

weight (+0.001grams) eff. capacity (+1mAh)
#1 26.021g [26g] 2031mAh
#2 25.887g [26g] 2030mAh
#3 25.953g [26g] 2036mAh
#4 25.967g [26g] 2036mAh
#5 25.955g [26g] 2036mAh
#6 26.068g [26g] 2063mAh
#7 25.988g [26g] 2032mAh
#8 26.042g [26g] 2034mAh
arith. avg. 25.985g 2037mAh

Eneloop AAA (HR-4UTGA):

weight (+0.001grams) eff. capacity (+1mAh)
#1 11.700g [12g] 820mAh
#2 11.708g [12g] 832mAh
#3 11.593g [12g] 812mAh
#4 11.722g [12g] 827mAh
#5 11.810g [12g] 825mAh
#6 11.731g [12g] 823mAh
#7 11.757g [12g] 825mAh
#8 11.793g [12g] 824mAh
arith. avg. 11.727g 823mAh

These numbers become relevant when you want to add the 1x Eneloop cell weight to (or substract from) the weight data given in flashlight reviews, manufacturer ads, and similar. Safe rounded values to use in your calculations are 11.7grams for 1x AAA Eneloops, and 26.0grams for 1x AA Eneloop Glitters. Sorry, i dont own any white AA Eneloops :p

adding to this thread. with my new accurate DMM and the C9000 i was able to measure that with an Eneloop AAA and -200mA discharge rate the C9000 discharges down to 0.90V (under load) and that this equals an offline voltage of 1.05V. Once offline and resting, the Eneloop AAA would then recover up to 1.19V within 2.0hrs. If you let the cell rest even longer, the stationary voltage point could lie even higher.

from these numbers you can calculate the sag to 0.15V and the recovery to 0.14V minimum, which makes a total of 0.29V (relative voltage).

*fyi* A so-called battery tester declares a cell dead when the sag approaches 0.0V. At that point the cell (e.g. Alkaline Duracell) might still bear a rest offline voltage of e.g. 0.3784V but this "amount" of absolute voltage is good for nothing (good for nothing like many of kreisler's smarta$$ posts haha).

For more on discharge and charge rates for Eneloops and Eneloop chargers please refer to the thread Where to get eneloop + charger?, thanks.

EDIT: after 1.0yrs the cell's capacity decreased a bit. the more relevant data is posted in veer's thread.

Thanks for this ChibiM! I didn't know that there where new colored eneloops out there and I didn't even know they were numbered. I have 16 each of the tones, glitters, costco tones, xxeloops and a ton of white eneloops.

Now I need to add the new ones to my eneloop collection.
