Average Reviews:
(More customer reviews)This new eneloop package (Sanyo Eneloop Ni-MH Charger and 8 Rechargeable AA and 4 Rechargeable AAA Batteries) contains 12 of the 2nd-gen eneloop cells, and the MQN06 4-cell charger. Note that unlike the previous eneloop Power Pack Kit, there are no C- and D-shell adapters in this package.
The rated capacities of those new eneloop cells are the same as that of original eneloop: 2000mAh for AA, 800 for AAA. All batteries are made in Japan. The charger is made in China.
I have tested 4 new eneloop AA cells, using my La Crosse BC-900 Battery Charger:
- Right out of the package, the average remaining charge is 1557mAh (min=1551, max=1564)
- After just one charge/discharge cycle, the average capacity rises to 2100mAh (min=2070, max=2130). This is 5% higher than the rated value!
Date code embossed on the AA cells is "10-04 0Y". I assume that means April 2010. Note that just like the old eneloop, the new ones are only charged to 75-80% when leaving factory.
According to the package and also Sanyo web site, the new eneloop is supposed to offer the following advantages over the original:
- "Holds charge up to 3 years" (85% after 1 year, 80% after 2, 75% after 3)
- "Recharge 1500x" (vs. "1000x" for original)
- "Suitable for temperature as low as -20 degree C" (vs. -10)
In real life, it is nearly impossible for the user to experience those benefits. If you recharge the new eneloop twice every week, it will take 15 years to reach 1500 cycles! Also the new self-discharge rate is not much different from that for the old eneloop (which claims 85% after 1 year, 80% after 2). So it is probably not worth paying an extra premium over the old eneloop, just for those perceived benefits.
However, there is one visible benefit for the new eneloop: it comes in different colors!
- The 8 AA cells consist of 4 light-blue and 4 dark-blue
- The 4 AAA cells consist of 2 light-green and 2 dark-green
This makes it easier for the new eneloop to be arranged in groups. For example, you may use one color group in your camera and another group as spare. Plus the new colors looked very nice, too.
The charger included in this package, on the other hand, is a big let-down. It is the same old Sanyo MQN06 which is slow and only charges in pairs. It is simply inexcusable that Sanyo continue to package their best rechargeable batteries with their worst charger. In my case, the price I paid (at a local warehouse Club) is cheaper than buying 12 new eneloop cells separately, so I just tell myself that the charger is thrown in for free. Otherwise I would subtract one star from the rating.
[Update July 29, 2010]
I have tested 4 new eneloop AAA cells, date code "10-05 0B":
- Average remaining charge out of package is 619mAh
- After two more charge/discharge cycles, the average capacity reached 830mAh.
That's what I like most about those eneloop cells (both new and old). They are highly consistent, and their measured capacities are usually higher than rated values.

Long term self-discharge data: I have tested a pair of new eneloop AA cell, after nearly 4 months (115 days) of storage. The average remaining charge is 89% of full capacity. This result is slightly better than that of the original eneloop, which usually reatins about 87% after three months. But the difference is within margin of error of my experiments.

Even though the self discharge of the old eneloop was already very impressive, you can store the new eneloop for 3 years and still it will retain 75% of its capacity.* You need a battery, which is reliable even when having cold temperatures? Before eneloop was suitable for temperatures as low as -10°C - now even until -20°C.* The new eneloop is even more environment-friendly as it is pre-charged with solar energy in Japan.
