NiZn-Nickel Zinc batteries question

[guiri]

Guys, I just heard of these NiZn batteries that are 1.6v or something in AA size.

Can someone explain the advantages of these other than the obvious that you can now run stuff that normally wouldn't run on rechargeable (1.2v) AA's and is there anywhere I shouldn't run them?

Also, is Powergenix the brand to buy or what?

What about chargers? The one that they sell or what?

Thanks

George

Your answer is in post 2 of this thread. :thumbsup:

Alright, how about this?

"and is there anywhere I shouldn't run them?"

Did you also read post 3 of that thread? Did you follow SilverFox's link?

I've been using the NiZn batteries for a few weeks now and i like them a lot for flashlights. They give a nice boost in terms of brightness and have pretty much the same characteristics as NiMh batteries in terms of discharge curve, self discharge, little voltage sag. Just make sure whatever you're using them in can handle the extra 0.4v boost per cell. I used 2 of them in my minimag 2aa and it fried the bulb in less than an hour but it gave quite a boost in brightness! And yes Powergenix is the company to buy them from, i got mine from amazon. Make sure to get the 1HR charger combo.

I did and I still need clarification/I need this simplified

cman, so how do I know if the device can handle the extra voltage? I mean, it's not like it's going to say so in the manual..

Thanks

If an electronic device doesn't give you specifications for its input power, then assume it can't. There isn't any magical way to know.

Your best option is to search to see if someone has tried the device you're curious about with either NiZn specifically, or something with similar or higher voltage characteristics, like a lithium-based battery.

These NiZn batteries are currently special-purpose, not a general replacement for the more common chemistries.

Yeah, I was curious if there were any general guidelines so to speak.

ni-zn are absolutely safe in 1AA led flashlights, at 90% are safe also in 2AA lights, but can become a problem in 3-4 or more configurations

on digital cameras, are very good with 2AA cameras, somebody use them also in 4AA cameras but someothers have damaged the 4AA external flash of some DSLR

usually if a manufacturer allow the use of lithiums AA so there shouldn't be any problem with ni-zn, if he say to don't use lithiums, so don't use ni-nz

I'm using 4 nizn AAs in my PT 40 with a 5 cell Mag bulb; runs great and is withing bulb specs.

Thanks guys and by the way, here's something I ran across on flashes http://strobist.blogspot.com/2010/01/new-nizn-batteries-offer-lightning-fast.html
