Power Genix NiZn AA cells
Today, we’re going to have a look at the Power Genix NiZn AA cells.
These were supposed to be a competitor to the NiMH with its high voltage of 1.6V, comparable to that of Alkaline cells.
Thus, they were supposed to power electronics that were used to alkaline’s high voltage for a longer period of time, compared to NiMH’s 1.2V.
Here’s the official specs:

I got these cells from FastTech here: http://www.fasttech.com/products/0/1189301
They came in a solid 4xAA case:
The cells were wrapped in twos with shrink wrap.

Comparisons with a Sony LSD cell:
Comparisons with a Duracell:
I’d say the size is pretty average. It shouldn’t have any length or diameter issues with any appliances.
And I finally got to play around with my charger and got some discharge graphs:
Extra credit: Does anyone know how to combine the voltage together in Excel?
My data looks like this:
The x-axis of capacity isn’t uniform, so I’m having some issues…
Anyways, one thing to note is that NiZn cells should be measured in terms of Wh, instead of mAh/Ah since they have a lower capacity due to the high voltage. That’s why I’ve included the Wh measurement as well.
Thanks for looking, and I’ll try to add some real world applications.
Please feel free to ask any questions.
