I am wondering if anyone is currently using, or has used these Nickel Zinc (NiZn) rechargeable & recyclable batteries.
As far as I am aware there is only one manufacture for the NiZn batteries, and that is PowerGenix.
Unlike the typical AA Nickel Metal Hydride (NiMh) which are rated @ 1.25 Volts, the AA NiZn are rated at 1.60 Volts. The Alkaline AA is rated at 1.5 Volts
NiMh voltage is 83.33% of the standard Alkaline/Lithium Battery, while the NiZn are 106.67% of the standard Alkaline/Lithium Battery.
The higher the voltage the lower the current, so I don't see any theoretical issues, but I am not familiar with the design margins of the circuits used in the DSLR's or Strobes, but know that generally the higher current is more of an issue than higher voltage in electronics. As far as I am aware, Photography Electronics are all approved for use with NiMh Batteries which implies they have a negative voltage design margin of more than 17%, so I suspect that they should be able to handle a 7% over voltage without any negative effect.
Anyone know anything different?
