So it is not a 3rd generation eneloop (HR-3UTGB) as shown in the ad but 4th generation (BK-3MCCE) signed Panasonic. However I doubt that we can still find the third generation on the market or even that Panasonic has made real change on the stack (a push definitely specification to 2100 instead of 1800 cycles with the same stack history to justify its logo lapposition ). Still have quality batteries that I use for several years and then until now perfectly keep their promises. Example: The little nephew who lands more batteries in the Wii controller! Hop I spring a game of heads I have not touched for more than 18 months and the controller displays a full charge. Great, feat never reissued with other brands of rechargeable batteries yet and I've tested the Duracell, Energizer, Sony before falling on the Eneloop.
