PowerGenix NiZn Review Test with Vivitar 285HV strobe & SANYO eneloop and 2700 batteries

Buy NiZn batteries here: http://amzn.to/eJuB54
Here was a quick little test I threw together after reading soo much about the PowerGenix NiZn AA Batteries. I have read good things and bad things about them..

Good things
They have about 30% more capacity than NiMH
runs at 1.6 V instead of 1.2 which should provide faster recycle times with a flash
GREEN!!! NiZn batteries use no heavy/toxic metals (mercury, lead or cadmium), or metal hydrides (rare earth metals) that are difficult to recycle. Both nickel and zinc are commonly occurring elements in nature and are not very hazardous. Zinc and nickel can be fully recycled. - ( wikipedia.org quote )
They actually weight LESS than a NiMH battery

Bad things
You wont get as many flashes out of these batteries.
You NEED to buy their own special charger i recommend going with the 1 hour charger its very inexpensive and comes with 4 AA batteries.
Some say they might be too powerful and if you pop your flash too many times in a row they will actually cause your flash to either over heat of just break/malfunction.

I setup my vivitar 285HV and tested the PowerGenix NiZn Batteries along with the Sanyo Eneloops 2000 mAh AA batteries and the Sanyo 2700 mAh AA batteries. Check the video for the results of the recycle time on the flash.

I will still need to spend more time with these batteries to see if the fear of over heating or breaking your flash is possible but I would say like anything else don't be a crazy strobist popping full power flashes just because you can... remember be a responsible flasher ;) and watch your heat!

the 2700 does not offer faster recycle time , only more shots !

Energizer out preforms these two options in my own comparisons.

I'm not actually Lindsey "Lee" by the way. ;) Hopefully you can take a joke.

Lindsey Leigh says...

A higher mAh value doesn't produce a faster recharge rate. mAh can be thought of as the maximum amount of charge a battery can hold, because thats exactly what it means. So your shits all fucked up and you sound like a tard. Sheet. I just noticed pixima beat me to the punch. Screw it... I'm posting anyways.

Hi where did you get those cases

A simple test using a Bower flash resulted in electrical failure when using NiZn batteries as a power source. The test was performed with a remote to prevent current from entering a $2,800 camera. The power of the NiZn exceeded some solid state electronics ability to cut off power. Using a cycle of 1 second resulted in electrical damage of the flash trigger. Most good flashes have a cycle time that can exceed 1/100 of a second. I would not use these in my Sony HVL-58am. Dr of Engineering

This is actually a pretty good test of the power of these batteries: Volts x Amps = Power. The higher volt NiZn causes more power to be delivered in shorter time. Not a good test of capacity since he didnt exhaust each battery set from a full charge,

[redcarpetphotography]

pixuma is right. mAh is like how much petrol the tank can store, nothing about power output. If a device uses 2000milli amps per hour then a 2000mAh battery will last 1hr.

[pixuma]

mAh is a measure of capacity...

Great video!!!
