Rewrapped eneloops have been a fairly common topic of debate. Some people claim certain batteries to be eneloops. And some of them may even be. But since FDK is owned by Fujitsu there are more and more batteries out there that have a "eneloop" inside of them. That being said, if you follow the following list carefully, you`ll see that they are not always one on one copies. There is even a 4th LSD battery so to say that is not sold under the Panasonic eneloop brand at the moment. If you look carefully it will explain why I say this.. Read carefully between the lines. Good luck 😉
Please note that the following list is as much as I know, and only be taken as my understanding. Another thing to clarify again is that "generations" doesn`t mean a certain age, but more of a quality difference. It is impossible to know what generation is used for a certain brand. It is likely depending on the buyer (in this case a brand) who gets what generation for what price. Some of the following batteries even indicate (by specs) a different generation than currently is being sold as the latest eneloops. Also it is very important to note that not all FDK batteries are part of the "eneloop family". Think about the Panasonic 2700 etc. I will post (mostly) the batteries that have a clear resemblance with their eneloop counterparts.
Sanyo sold white Harmolattice AA cells from 2009. They use the same coding HR-xUQ as eneloop lite which were introduced in 2010. And have the same specs as well.
950mAh minimum for AA. 550mAh minimum for AAA The interesting thing is that they were specified as 1000 cycles, while (most) eneloop lite were rated at 2000 cycles from announcement in 2010.
Sanyo sold Harmolattice AA cells in the east Asian region. They are the same as Eneloop XX/PRO. The only difference is that the Harmolattice do no come pre-charged while the XX are pre-charged. You can also see that in the text underneath the Harmolattice name, powered by eneloop. The same cells, just a different wrapper. I believe they were available since 2010.
2500mAh typical and 2400mAh min. capacity.
75% charge left after 1 year when fully charged.
Specifically branded Muji for the Muji stores in Japan. They were available for 1280 yen for a Charger including 2 batteries coded MJC341FX(CX) as a set from 2012.
950mAh min for AA HR-3UQ-MJ-2C and 550mAh for AAA HR-4UQ-MJ-2C. (2C meaning 2 batteries) Both rated 2000 cycles. Just like eneloop lite. Which they are, using even the same code.
Keep in mind that in certain markets a code is attached behind the product code. For example HR-3UTC becomes HR-3UTCEX. The last 2 letters are only an indicator for certain markets or amount of cells in a package!
The list below is ordered by Product code, not by production date.
Product pictures as well as packaging can vary depending on the region.
These seem to be the same as 2nd edition eneloop standard.
There is also a picture for the Japanese HR-3UTA
1900mAh min capacity. Rated for 1800 cycles. 70% charge after 5 years.
Never been available in Japan as Fujitsu branded. Just as HebelHaus brand. Mainly avaialble in Europe and Asia. They seem to be the same as 2nd gen eneloops, which is rather strange when you look at the code, after the UTA. Picture is from the Shoudian forum. Cant find an original product picture unfortunately.
Min. 1900mAh capacity. Lifecycle rated at 1500 cycles. 90% charge remaining after 6months 85% after 1 year.
Popular battery. Which is the same as the 4th generation eneloop std with the same specifications.
Capacity 1900mAh. Lifecycle rated for 2100 cycles. Charge 85% remaianing after 1 year or 70% fater 5 years. New updated specs show 70% charge left after 10 years.
These seem to be only available in Asia. Not available in Japan. Please take a look at the details below to see some interesting numbers. These would imply a 4th type of "eneloop battery". As they are rated for 1000 cycles. Which would help some people to understand the "generations" when talking about rewraps. See the Korean Blue Fujitsu. Which I think are called 4UTD. Keep reading!
They are also known as Fujitsu HR-3UTI in certain countries! They are cheaper to get then the 2100 cycles.
Capacity is 1900mAh for AA. Lifecycle of 1000 cycles, with a charge remaining of 80% after 1 year.
The High Capacity cells. They have never been available in AAA format in the Fujitsu branded lineup. These are equivalent to Eneloop Pro 1st gen, which also never had an AAA version.
These cells are only available in Japan. HKJ reviewed these batteries for me.
Capacity for AA min. 2400mAh. Lifecycle rate of 500 cycles. Remainaing charge left: 75% after 1 year.
These are the first AAA "pro" fujitsu NiMH cells that were in production. Also they now changed to black wrappers. The English package is a little different. These are the same as eneloop Pro 3rd and 4th gen.
Black: AA 2450mAh min. capacity 500 cycles 85% 1 year. And 900mAh for AAA.
HR-xUTHC is the same as the 3rd/4th gen eneloop Pro. With the same specs. The funny thing is now, May 2017, there is no equivalent to the latest eneloop Pro BK-3HCD with 2500min capacity.
Black: AA 2450mAh min. capacity 500 cycles 85% 1 year. And 900mAh for AAA.
Specs and everything look the same as HR-3UTA. There is no AAA version for this type. I don`t know why they would include this in their line-up. Maybe just for certain markets.
Green: 1900mAh rated at 1800 cycles. And 85% charge reamaining after 1 year and 70% after 5 years.
These are the Lite version. They exhibit the same specs as eneloop lite. There is no direct AAA available, but it looks like the lite version available in Korea has an AAA version as well. But I couldnt find the product code. Another interesting thing is that they show 5000 cycles, while they are rated at 3000 cycles for the eneloop lite, and only for the Chinese eneloop lite they are rated at 5000 cycles. But these are made in Japan, not China.
Pink: lite 950mAh for AA. 5000 cycles 85% charge remaining after 1 year and 70% after 5 years
There are a few variations of the Toshiba Impulse, so only the following list can be considered eneloop batteries. The previous version which are also tested by HKJ were made in China.
The High end version of these batteries. These batteries are equivalent to the eneloop Pro. On the bottom of the picture you can see an orange Recycle Symbol, and next to it on a yellow background written. Made in Japan (in Japanese: 日本製 , nipponsei)
Impulse 2450mAh capacity. With a rated cycle life of 500. And 85% charge remaining after 1 year.
These are even called Toshiba Impulse Lite. The back of the package shows FDK product. They show 5000 cycles while eneloops show 3000 cycles for their Japan made ones. The eneloops may be a different generation, or it is just the print.
Toshiba Impulse Lite 950mAh for AA batteries. And 5000 cycles with 85% charge remaining after 1 year
Unfortunately specs on Amazon can be conflicting. So be very careful with the batteries you order. I would just say: Go for Japanese made Eneloops instead. At least you can be sure they are good. The Amazon descriptions can be weird. Some pages say Made in Japan, while on the bottom of the same page it says origin: China.
Please take a look at the Fujitsu list above. Do you see a resemblance? Also there is no AAA version made by Fujitsu with the same code, only AA. These are High Capacity cells. Like 1st gen eneloop pro. It also says Pre-charged using Solar energy.. which eneloops also show.
Amazon Basics Grey with green line: AA 2400mAh 1 year 75% charge remaining, 3 years 65% remaining.
They sell rechargeable batteries for a long time. Only since a year or so they sell IKEA Ladda with a simple white and a beige design. Please note that the earlier versions with green and silver are made in China.
AA: article nr: 703.038.76
AAA: article nr: 903.038.80
They look like the Pro version eneloop. There is no product code besides its article number. Made in Japan definitely indicates FDK factory, as there is only 1 LSD NiMH factory in Japan. Not clear what generation they are. White colored.
2450mAh 500 cycles for AA, 900mAh for AAA. No indication of remaining charge after X years.
AA: article nr: 203.038.74
AAA: article nr: 303.038.83
Again, these are not 1 on 1 comparable to eneloop. But overseas companies like Amazon, Powerex and Duracell seem to be using slightly different specs. Maybe they have to do that. Im not sure.
Lite usually has a much higher rated cycle life than these... Tan colored.
1000mAh 1500 cycles for AA, 500mAh for AAA. No indication of remaining charge after X years either.
Duracell has some DX1500 coded batteries that are made in Japan. For me its just too vague because they use different kinds of packaging and names. Some say Stay-charged, Rechargeable plus, Ion Core or Active charge, Duralock etc. Those are already 5 types of packages for the DX1500 batteries. Some show 300 cycles, others 400 cycles. Some say DX1500H other DX1500. So they might be some sort of eneloop pro. It`s just too much work to find all kinds of packages to show them. Plus there might be fakes out there as well. Some think they buy Japanese cells, but receive Chinese. Some of the packages are just confusing, and online sellers usually know too less to see the difference.
They use codes like: MH-4AA270-BH for their 2700mAh (which of course is typical capacity and not minimum capacity)
MH-8AAPRO-BH for the latest Pro edition 2700mAh typical capacity. These to my understanding are Not eneloop batteries but Panasonic High Capacity HSD (or hybrid LSD if you wanna call them that way) batteries. Similar to Panasonic Evolta high capacity 2550mAh or Panasonic 2700mAh for the overseas market.
This is entering a gray area. Just like some Powerex and some Duracells are made in Japan. Its just not very clear which are which. I hesitate to post them.
First of all, the code B4 is just the amount of batteries in a pack. The 2-packs are coded NH-AA-B2K. Nothing more, nothing less. These seems to have different specs as well. Probably because they are available on overseas markets.. Dont know for sure why they have different specs. Probably 1st gen std batteries. They also had a different wrapper, probably as an earlier version. Please note that the NH-AA-B4KN and NH-AAAB4KN are made in China and are different batteries!
AA min. 2000mAh rated for 1000cycles, and 85% charge after 1 year. AAA min 750mAh.
High capacity cells. I just can`t find enough specs for this battery. Therefore I`d like to put an extra warning here. They are made in Japan, but I just have too less info on these. This is just 1 reason why I don`t like to put any eneloop. Again the AAA version looks strange.
AA min. 2400mAh AAA min 840mAh. That`s all I have.
