PowerGenix has developed a high-energy density, high-cycle life and low-cost nickel-zinc (NiZn) battery ideal for applications that demand high discharge rate capabilities.
The technology offers compelling performance advantages, most notably a 30% weight and size reduction coupled with higher power and superior low temperature discharge behavior.
Using both a patented electrolyte and a patented electrode composition, PowerGenix has eliminated past issues of dendrite formation and shape change of the zinc electrode during cycling. Dendrite formation and shape change of the zinc electrode have been the primary hindrances to a commercially viable rechargeable NiZn battery. Additionally, PowerGenix developed this breakthrough technology in a manner that did not compromise the inherently superior performance characteristics of a NiZn battery.
Two of the more prominent features of the PowerGenix NiZn battery are its small size and low internal resistance, which enables the delivery of significantly more power during periods of peak demand than a nickel-cadmium (NiCd) or nickel-metal hydride (NiMH) battery of comparable size.
Although the design and construction of the cell is similar to NiCd, the higher voltage of PowerGenix's NiZn cell results in a 25% lower cell requirement in multi-cell packages, representing significant space and cost savings | |

 A good alternative to Ni-MH batteries for some uses Jul 27, 2010
There are basically two reasons for using this chemistry, environmentally friendly and higher voltage. An advantage to this chemistry compared to regular Ni-MH is that it has a low self-discharge rate. Reportedly, similar to the low self discharge Ni-MH batteries. The higher voltage may or may not be suitable for any particular device. I suggest that things with high current draw or that were designed for 1.5 V alkaline cells will like the higher voltage. Flashes (more on that later) and digital cameras are good candidates.
The down side is that NiZn do not have quite as much capacity as Ni-MH, even when the higher voltage is factored in. The other negative is that they have about half the rated life compared to Ni-MH, so expect to replace them sooner. This is mitigated by them being cheaper and environmentally friendly. Besides, 500 charge/use cycles is not bad at all.
I bought these to power my Vivitar 285HV & non-HV flashes. This was an experiment, but has gone well, so I intend to get a another set soon. The big bonus is not with capacity, but that the higher voltage kind of super charges the flashes. Essentially they almost cut the recharge time in half. Here are my findings, comparing NiZn against fresh, high capacity Ni-MH.
285 non-HV Full power
Ni-MH 6.5 sec
NiZn 3.5 sec
285HV
Ni-MH 7 sec
Ni-Zn 4 sec

 Power is Great, Quality is Lacking Jul 17, 2010
Power:
I only use the PowerGenix in flashes when I want faster recycle times and don't have enough pictures to take to justify a power pack. The flashes (Nikon an Canon) seem to love the higher voltage and recycle noticeably faster.
Quality:
My eneloop batteries (I have many), after charging or after use, generally have a voltage difference between the four batteries of less than .05 volts. The PowerGenix are all over the board. One reviewer mentioned that one is usually drains more than the others. Very true. One extreme, for example, was 0.6 volts vs 15+ for the other three. Even immediately after charging, the voltage difference is often more than 0.5 volts, and that while being careful not to charge batteries together when their voltage differs by more than one volt.
For power, they do the job. For a quality battery, look elsewhere.
Best rechargeable batteries I've ever used! Jun 14, 2010
I received a POWERGENIX charger and 4 2500mWh NIZn 1.6v rechargeable batteries as a gift. I had used other rechargeable batteries mainly in my digital camera which uses 4 AAs. I bought an ASSIA charger and 12 2800MAH batteries. I'd have 4 in the camera and 4 as standby. The batteries didn't last long and I was always recharging. But with these new-type rechargeables, it's a different story. The POWERGENIX NIZn rechargeable batteries just last and last and you have to be amazed at the longevity between charges. Because they are superior to any rechargeable battery that I've used for my digicam, I bought 4 more for my wife's digicam although it uses 2 AAs. The seller had the best price and the delivery was quick. I am totally satisfied by the seller and the product and I highly recommend both.

Call it Hype if you want BUT they work!!! May 18, 2010
I have a digital camera, that I like a lot, that I retired because it just went through batteries so quick, 2 to 3 sets a day. I bought these batteries and the camera lasted all day, so it is officially out of retirement. So dont know what your results will be but mine were awesome.

Long battery life Mar 17, 2010
These batteries works fine with all my devices: wireless keyboard, wireless mouse, wii mote, other remote controls, clock, portable CD player.
To test battery life and self-discharge rate, I put them into my wireless mouse and clock in early Dec, 2009. After 3 months, the wireless mouse run out of battery; the clock is still running fine. I need more time to know how long it can power the clock. But clearly these batteries can hold their charge > 3 months.
Power wireless mouse for 3 months is much longer than normal NiMh batteries.
