Eneloops Made in China

Panasonic Eneloop standard (made in China)

  • AAA: BK-4MCCE 2100 cycles. Min. 750 mAh
  • AA: BK-3MCCE 2100 cycles. Min 1900 mAh
  • Not available in C or D size
  • till 2016 AA and AAA: Claimed 65% capacity left after 5 years (*3) This is how you easily can see these are made in China
  • from 2016 AA and AAA: Claimed 70% capacity left after 5 years (*3) This is how you easily can see these are made in China the newest ones made in Japan have a 70% capacity claim after 10 years
    So the previous Japanese cells would mention 70% 5 years, so it can be a little confusing in some regions to distinguish Japanese from the Chinese ones. 
  • Launch date AA and AAA: 2013 (*2)
  • Made in China!

Eneloop Lite (Made in China)

  • AAA: BK-4LCC 5000 cycles Min. 550 mAh
  • AA: BK-3LCC 5000 cycles Min. 900 mAh
  • Not available in C or D size
  • Only on the Japanese market
  • AA and AAA: Claimed 75% capacity left after 3 years (*3)
  • Launch date AA and AAA: April 2013 (*2)
  • Made in China!
  • (I find it strange that only the Lite eneloops that are sold in Japan are actually made in China, and that the whole eneloop export market receives Japan made Lite eneloops. From 2013 till about 2015-2016 eneloop lite in Japan were made in Japan. Since then they source eneloop lite from China for the Japanese market.

Read more about eneloop coding.   Date codes and more>

*1= I couldnt find the actual date of production and couldn’t find the claimed % after a year

*2= This is the date they became available. Usually the announcement date is a few weeks before the available date. Also, in some cases, certain batteries were available overseas earlier than Japan. In the cases where I couldn`t find a date, I omitted it. 

*3= years of storage. This indicates a full charge, and left unused in storage at a certain temperature. The remaining capacity

*4= in Japan they stopped showing the rated capacity. And only showed the minimum capacity, eg. 1900mAh for AA basic eneloops

*5 A/E bk-3mcca bk-3mcce are labeled for the overseas markets. Please check the explanation on eneloop codes for all the info. 

*6=4th gen std updated with 10years shelf life were first available to the overseas markets.. Japan showed a 90% claim for 1 year. In 2016 Japan also shows 10 years 70%. 

*7= A very strange things to see. Chinese cells being sold in Japan.

*8=Eneloop XX named on western market 2010, Eneloop Pro on Japanese market 2011, since 2014 worldwide : eneloop PRO.

*9=WXA was never available to the Japanese market. It also has the same specs as the first generation. But to keep it easy, I call these 2nd gen because they have a different coding. Which usually indicated a different battery.

*10= As far as I can tell there is no indication of typical capacity anymore. The European packages also don`t mention a typical capacity anymore, only min. capacity
