1.3 volt mercury batteries

    I have an old Nikon FTN, that takes the .13 volt mercury battery for the
    meter.
    All mercury batteries have been banned in the U.S., though it is not illegal
    to personally
    import them from an overseas or Canadian vendor.
    Has anyone been able to do this successfully?
    Alkaline batteries lose their voltage quickly and basically don't work and
    there are no 1.3 volt alkaline batteries. 1.5 volt batteries result in non
    accurate metering.
    Thanks for any help.

    There are zinc air replacements. Its the odd voltage that is the problem
    rather than the ingredients of the battery.

  3. C.R.I.S. http://www.criscam.com/ makes adapters to use small silver
    oxide batteries in place of various mercury camera batteries. The
    adapter adjusts the voltage and matches the size of the mercury
    battery. There is a selection guide on their site. I have one of
    these for an old Olympus and it works fine.

    WEIN makes zinc-air batteries that also work in this application.
    These are available from most large camera stores. They have a long
    shelf life until activated by removing the seal tape but have a shorter
    storage life after activation.

    A web search will result in lots of sources for mercury batteries.

  4. No one makes them any more.

    See www.criscam.com for what is generally considered to be a good
    alternative solution. Look under "MR-9 battery adaptor".

    It is illegal to ship them through the US Postal System and some parcel
    delivery companies have restrictions or require declaration of
    contents. Mercury is considered a toxic chemical. It's not the
    mecrury that's hazardous but the vapor in a confined space, box,
    container, etc.
    People have probably done this despite the laws.
    Some camera repair shops will readjust or modify the power supply and
    light meter for silver oxide 1.5v batteries. Silver oxide and mecrury
    batteries have similar discharge curves.

    You can get your meter recalibraited to use modern batteries.
    This guy is the best as such things:

    Just use the 1.5 volt cells and use a handheld meter to calibrate you FTN
    meter.
    You can adjust it using the ISO/ASA setting. You need to do this anyway as
    different
    type of films require their own settings (from B/W to chromes).

    I you find a FT2 this camera uses modern cells.

  9. In my Canonet, I just use a Silver Oxide battery (some aluminum foil to make
    it physically fit) and reduce the film speed setting by 2/3 of a stop (e.g.
    set it to 260 when using iso 400 film).
