    unlikely, the flash need batteries in the battery compartment to power up the LCD, and the high current from battery pack is to go straight to the capacitor for powering the flash.

    If you don't believe, can always buy the battery pack and try for yourself.

    I suggest you try cleaning the battery compartment:

    Wear gloves and face mask
    Remove the leaking batteries
    Wipe away the wet leaks from the batteries, these are the corrosive substance that damage the contacts and electronics, when its dry, its whitish in color
    Use cotton bud lightly damped with vinegar and slowly clean the corroded metal contacts
    Make sure the flash is dry and test again with batteries
    The flash will power up again if the battery compartment is properly cleaned

    Do at your own risk. If you die, get poisoned, electrocuted or get injured, I am not responsible.

    Or alternatively, you can send it into Nikon Service Center to get it repaired.

    And yes, you need batteries in the flash for the flash to work even with a battery pack connected. It is not "so easy to say"... people here know it because some of us actually tried it...

    In front of the battery chamber is the power PCB, at the back is the main PCB that contains the microprocessor that controls all the flash function and operation. A leak on these boards would be catastrophic. The boards has to be replaced if there's corrosion.

    What Catchlights mentioned is true. The main PCB needs power supply to the microprocessor that drives the LCD and all other functions. The battery pack will only supply direct high voltage to the capacitor for fast charging.

    yes, may things in photography is so damn easy, it only takes you 25 years to figure out. lol

    anyway, I spend a few years to study how to DIY battery pack before...
    there are two type of external battery pack, one is connect to flash thru the flash battery compartment like Quantum Battery One+, since your battery compartment is already damage, so this type of external battery pack won't work.

    another type of external battery pack like original Nikon SD-9, like I said, it connect to the flash socket, but you still need to have AA batteries to power up the LCD, so it is still no good.

    it is not say unrepairable, but most likely not justify the cost of repairing the flash, you can send it to Nikon Service Center to find out more.


    so never never leave AA batteries inside battery compartment for too long, especially Alkaline battery.

    Since I had the 'privilege' of having to send an SB900 for servicing at NSC recently, thought I'd share my experience.

    Had similar issue with batt leakage. Visible corrosion on battery contacts. Would not power up with fresh batteries.
    Tried DIY cleaning with cottonbuds+white vinegar, didn't work.

    This was actually the second time I'd sent the flash in. The first time, the technician managed to get the flash working by a quick cleaning of the contacts. FOC. Was quite glad.
    But it stopped working after a week or so. No choice, had to go back again.

    The staff will advise you on estimated cost, which depends on the extent of the damage.

    My initial estimate was about $300+ for replacement of:
    1) battery contacts
    2) battery chamber
    3) battery lid
    4) printed unit (assume this is their term for the PCT).

    After opening the unit, they found that the leakage had not affected the 'printed unit'. Whew.

    My repair cost came up to $140 eventually.($70 for labour charge, $60 for parts, before GST)

    A $140 lesson: Always remove batts when not in use.

    People take time to read and give answer from his knowledge which you don't want to hear, you don't like... SMS you some more...

    Just wait for the fluid to evaporate and your flash will be ok, don't worry

    Don't be a full. Who would want to trade perfectly fine items for trouble and wasting time and money fixing?

    It is always good to hope, even for the impossible.

    Yep just like me hoping that my D7000 will magically transform into a D4. I have faith that it will happen so I continue to hope :B
