That's cool. I wonder if the price will also go up considering the upgraded materials, etc.

They are indicating the new Eneloops can handle 1500 recharge cycles and will maintain 75% capacity after 3 years...
--------------
The latest breakthrough allowing "eneloop" to be recharged up to 1,500 times has been realized by applying newly-developed recharging technologies.
--------------
Rechargeable batteries typically have a "self-discharge" characteristic which gradually reduces charged energy over time. This is considered the downside of typical rechargeable batteries, as it renders them inconvenient since they are unusable immediately after purchase, requiring the batteries to be charged to start using them and recharged if they have been left on the shelf for a period of time. Since "eneloop" batteries have a low self-discharge rate, they can be pre-charged and usable immediately after purchase, like dry cell batteries. This new "eneloop" battery continues this tradition, and a fully-charged "eneloop" will be "ready for use off the shelf even after 3 years" of storage, according to Sanyo. By using SANYO?s original "super-lattice alloy" for negative electrode material and improvement of materials and structure, a fully-charged new eneloop battery can maintain "approximately 75% of charged power even after 3 years", ensuring that power is available when needed.

Mr. Happy had a set of new factory charged AA cells marked 2006-08 which sat unused for the last 3 years.
He tested them last week and they also achieved 75% after 3 years.

Wahoo...!
And, once again, I think it's commendable that Sanyo didn't succumb to increasing the capacity of the Eneloop at the expense of its durability and longevity.
Good on them.

I wonder when we can buy these, and how can we tell the difference between first or second generation Eneloops

They said they are giving them a different model number. Unfortunately they also seem to be indicating they will only be for sale in Japan.

It appears that Sanyo deserves even more kudos.
Firstly, they don't even show the Eneloop's typical capacity of 2000mAh on the cell any more. Instead, they only show the minimum capacity of 1900mAh.
As well, they are using a higher than necessary discharge rate to measure the remaining capacity. I believe the industry standard calls for a 0.2C rate, which would be 400mAh for a 2000mAh cell. Sanyo is instead using a 740mA rate, which would necessarily result in a lower capacity measurement.
While I think it's a good idea to set a trend by only showing the minimum capacity, which is what the consumer is supposed to be guaranteed, I wonder what is prompting them to use the higher than necessary discharge rate to measure remaining capacity?

i hoped that the new one will resist abuse even better and withstand higher discharge current without losing much of its capacity while more charging cycle doesn't meant much for us doesn't it?

Only Available in Japan? :ironic:
If they do test well...
Do I hear a groupbuy?

Interesting... I just looked at some Energizer rechargeables for the first time in a long time (since the poor charge retention debacle) today at Target, and noticed that they were rated 2300mAh, were marked as "New" and that the new feature was lots more charge cycles. I assume that Sanyo still makes Everready's cells...

Didn't read the article yet, but this makes it sound as if the extended cycles may require a specific charger?
Anyway, KUDOS to Sanyo. I've been so pleased with my Eneloops that I can scarcely imagine them getting better.

new press release, eneloop now in crayon colors, atleast in japan. http://sanyo.com/news/2009/11/05-1.html
i've been wanting to buy eneloop rechargeables for awhile now. currently i have none. i've resisted so far, waiting until the new ones make it to the us. not sure how much longer i can hold off.

Forget the colors, I want the "eneloopy" battery tester!
