Nicken zinc batteries?

Anyone tried these?

NO!!

You should check with the manufacturer to see if your "gizmo" can handle the 1.6V batteries instead of 1.2V. If you use 2 batteries then the voltage will be 3.2V instead of 2.4V. It doesn't sound like much of difference, but you never know.

Call customer service to see if its okay cause it would be a major ouie!!! if your gizmo burnt up from overvoltage. Some of the "computer chips" can handle only 2.6V or lower. And if you apply 3.2V, it may shorten the life of the "computer chip" inside.

Yeah, what smilingcat said.

The web page you linked to is just bizarre.

It's amp-hours, not voltage, that determines how much life your batteries will have per charge.

Are you using the latest highest-capacity NiMH batteries now? If you bought them several years ago, it's time for a new round (and recycle the old ones if you don't want them any more). They've kind of stabilized now, but when they first introduced NiMH, capacities increased by leaps and bounds. I think my first NiMH AA's were something like 1350 mAh, and they're up to 3000 now. Older chargers might not handle that capacity, so you might want to stay with 2300 mAh or less until your charger gives up the ghost.

I was given a sample of these. I don't find them to last any longer or provide brighter light (used in a Dinotte light) but I haven't done any real scientific checks - I will and report back. And it's just a pain to have to use their proprietary charger.

From their own FAQ

Will PowerGenix Batteries work with all devices?

The manufacturer does not guarantee compatibility and functionality of Nickel Zinc batteries with any device. Prior to use, please read user manual of each device to determine if restrictions exist as to which battery types may be used.

Amazingly, these got mostly positive comments on Amazon.

One guy said the higher voltage killed his camera flash and he will be testing other flashes to see what happens, but he still gave the batteries a five-star rating. Huh?

I think I'll stick to NiMH for now.
