While searching for an AA cell with low resistance, I stumbled across Nickel-Zinc cells. They have resistances on the order of a few milliohms to tens of milliohms.

I was pretty excited until I started reading the reviews of the PowerGenix cells. They seem to suffer from reliability issues. Do any of you guys or gals have experience with these batteries, or others of the same chemistry but from another manufacturer?

 

Have not tried them but they don't look attractive. Terminal voltage is not campatible with NI-MH or NI-CD, they don't provide increased run time. Obviously, poor reliability/few cycles means they are worthless.Maybe they are trying to capture the market for devices that must have the higher voltage of alkaline?
