endimion said: sorry have an issue with posting on that website lately.... so I was wondering if you had any good site to refer us to.... I'm interested by those batteries.... how do they compare to NiZN ???? I'm binging it right now.... but if you have some info source on hand I'd love to consult them.... thank you in advance... |
Based on what I've just read, while NiZn batteries may offer a greater voltage, they have a much poorer lifecycle. You'd be able to get 500 recharges out of the battery versus 1000 or more. Also, based on what I read, there aren't commercially available AA batteries. There are sub-AAs, but not AAs.
What I couldn't get a good fix on was what the mAH was. If you could get a AA cell with 20AH (10x the amperage of a 2000mAH cell), as are available in a much larger size battery, NiZn would be the best bang for the buck. They're long-life discharge rate, they offer a a higher voltage and amperage, they're environmentally friendly (in most countries we carry around zinc and nickel in our pocket change every day), and they would be cost effective.
But, thre are issues that the battery industry would have to completely workout first.
EDIT: To explain this better my conflict. Yes, the batteries only offer approximately 500 recharges, but at 10x the Amps, that works out to approximately the same as 5000 recharges. When you compare that to a 2000mAH (or 2AH) NiMH cell's 1000 recharges, you're looking at 5x the life.
