Made with safe, nontoxic Nickel Zinc (NiZn) chemistry, PowerGenix’s rechargeable AA batteries are a great choice for consumers because they provide the power level of a disposable battery with the environmental benefits of rechargeables. In short – they are the best of both battery worlds.

sucky  Time owned: more than 12 months
i have to update my previous review, these batteries work well for maybe 5 recharges then they wont charge or say they are charged but provide little use. they self discharge very fast too, forget about putting them in a flashlight cause 2 days later they be dead.

Great for certain apps  Time owned: 0 to 3 months
NiZn cells have a terminal voltage of 1.65v compared to NiMHs of about 1.25v. In some uses (voltage sensitive devices) NiCds and NiMHs just wont cut it, the voltage droops and the camera shuts down. These Power Genix cells really come in handy in those applications. They list 2500 mwh (not mah) as capacity. I tested them and they come out about 1100 mah on my Powerex 900 tester.
I use these in my Yaesu FT 817 and I get great performance. The only thing I wouldn't use them in is something with no regulator and uses incandescent lights, the higher voltage could cause shortened life. These are GREAT for photoflash devices, much faster cycle time and lots more flashes than NiMHs. Although they only tested at 1100 mah they seem to give just as much total power as my Eneloop AAs which test out at 1800 mah. I guess given the higher voltyage you'd have to do mwh (milliwatts rather than milliamps) comparisons to get a real picture of relative capapcity. They are being HEAVILY diuscounted on Amazon, a 4 pack of AAs with a charger for $14.19. The same pkg is $40 at my local Ritz camera shop right now. At the current online prices this is a no brainer. Buy some, you will like them.
