Thread: Nickel Zine Battery

  1. #1

    Default Nickel Zine Battery

    Dear Forumer,

    I read in the mass sales thread that there is new Nickel Zine Battery available, because this battery is having fully charge voltage of 1.8V as compare to1.2V for normal rechargable batteryies, will be able to re-cycle flash much faster.

    Has anyone use it before? What is your opinion and experience on this new technology? (maybe old technology)

    must see your equipment is design to accept up to what Volt max.
    higher volt will charge faster no doubt, but the equipment must be able to withstand the higher voltage.
    life is but a dream...

    I am looking at this Nickel Zine battery from 2 angles:

    1. Whether can the equipment withstand the high voltage? Since this is Photography forum, flash light recharge cycle is important, therefore can most of the flash gun take the higher voltage and does it improve the cycling time.

    2. Second important aspect will be the reliability of such battery: does it leak and damage the equipmnt, what is the life span, does it spoil easily?

    I think you mean Nickel-Zinc.

    Never used them, but just so you know, recycle times are more due to the internal resistance of the battery rather than its voltage. E.g. Ni-MH batteries are 'only' 1.2V but recycle flashes faster than alkalines (>1.5V)

    A ref for you http://en.wikipedia.org/wiki/Nickel-zinc_battery

    This article states that the internal resistance of Ni-Zn batteries is lower than Ni-MH, which does mean faster recycle times. But it also states that they have "lower volumetric energy density" which implies less energy (i.e. flashes) per charge.

    Is it safe for your equipment? Better check with equipment manufacturer, or the warranty may be void if something goes wrong.
    In theory for a flash that normally uses 4 x NiMH batteries, you could use 3 x NiZn instead.

    Thanks for enlightening, yes, I meant Nickel-Zinc (NiZn) battery.

    Yes, almost return all my electrical theory back to my lecturer.

    So a rechargable battery is characterised by:
    1. Open circuit voltage
    2. Internal resistance
    3. Energy store capacity
    4. Charging time
    5. Charging efficiency
    6. Self discharge rate (power retaintion period)
    7. Worsed of all is the chemical leakage that damage the equipment
    8. Price
    9. Special charger required
    10. Memory effect (to discharge before charging again)

    Ok, based on the above characteristic, how do we rate the NiZn rechargable battery, why is such NiZn battery not commonly seen?

    Appologize that I may sould like a young kid keep asking question one after another.

    Nissin doesn't support this battery.

    Since you are eletrical/electronic trained it should not be difficult to assess this NiZn battery.Take for example,Nissin officially states it's products does not support NiZn at 1.6V nominal (under load) with good reason.Being battery operated most designs will save energy by using low power ic chip in the control circuit.It may be 3V or even 1.5V so depending on series or parallel connection the combined voltage of NiZn battery may exceed the operating voltage limits of
    such ic.The chargers may just barely be able to charge at 1.8V because you need a little extra headroom for that what ever that is.But the major barrier may be the working voltage of the ic especially the microcontroller or brains.Lastly this being a revived technology and not in mass use or production ,more research needs to be done to see if it is efficient replacement for common NiMh batteries.However that does not stop you with experimenting with them if you can accept destroying your flash unit in the name of research.PS if there is voltage regulation (most likely),it may be possible to try.
