Still in the development stage

Certainly the best high-capacity AA batteries (the other vendors have this technology is still not under control, since the self-discharge is too high), but not yet as mature as the known 2000mAh variant.

Also Sanyo still struggling with the problem of self-discharge! While holding the freshly charged battery capacity well, 'but only until they are required, then it goes rapidly downhill.
In other words: In a power-hungry LED flashlight, the batteries while bringing outstanding performance in power and run time, but only when the battery is freshly loaded and unloaded in a train. Consumes one 2/3 of the capacity on one night (again out with the dogs), then almost no current is present 24 hours later.

Unfortunately, the supplied rechargeable batteries are not quite the same, three batteries demonstrated multiple discharge-charge cycles three batteries have a capacity of about 2400 mAh and only a good 2100 mAh. Again, you notice that the batteries are not yet really mature.

In summary: Surely the best high-current AA batteries, very good for all devices that need high amps, but with weaknesses. In contrast to the classical Eneloops definitely take spare batteries, otherwise you are suddenly in the dark!
