Summary of ways people fixed their Nikon Coolpix camera battery door latch

    The problem really goes back to the problem of having the battery door
    be part of the battery circuit, and having the spring contacts of the
    batteries putting constant pressure on the plastic door latch. Plastic
    will fatigue, get brittle in cold weather, and isn't tolerant of even
    momentary abuse.

    I've fixed battery doors several ways, but I tend to stay away from
    epoxy and cyanoacrylate glues, and of course duct tape. There is often a
    way to insert a steel pin or section of a paper clip into the plastic
    with some creative drilling.

    Type "camera reliability li-ion versus nimh" into the Google search box,
    and then click on "I'm Feeling Lucky." Click on "Advantages of Li-Ion
    Batteries/Disadvantages of NiMH batteries (AA/AAA)" in the table of
    contents, then scroll down to "Devices with Li-Ion Batteries are Usually
    More Reliable." Good explanation--oh, did I mention that I wrote it?!

    It's not just Nikon, other brands have similar problems, though Nikon is
    especially bad because it's not the door that breaks, but the camera body.

    Try to buy cameras that use Li-Ion packs, rather than AA batteries, as
    they are more reliable.
     
  2. Problem is that the AA batteries are more reliable because if I forget to
    bring them or if they run low, picking up another set of freshly recharged
    batteries or brand-new alkalines is a snap.

    The camera with a lithium ion battery pack is more often a brick than it is
    a camera, in my humble experience - due to battery pack problems. I never
    buy any lithium ion camera or any other device (telephone, miniature tv,
    etc.,) if it exists with AA batteries.

    AA batteries, in the long run, are vastly more "reliable" than any other
    type of battery pack (when you include the down time when you don't have a
    spare battery or a spare charger available).

    I do the same. I only buy cameras that take AAA batteries.

    And the same problem exists with laptops. Most are trashed because the
    batteries fail and are no longer available either at a reasonable cost
    or at all. I've saved a couple of discarded laptops by rebuilding the
    battery packs myself. But I was able to do that only with the NiCd ones.
    I don't even try with the Lithium ones.

    I've done something similar to fix the battery door on a portable stereo.

    I might do the same for my Nikon CP-5200 Iit apparently suffers from the
    same plastic weakness but uses a different door style, so I cannot
    effectively do the paperclip thing, whic is what I'd do if I had a 4200 or
    other camera as depicted.

    Those with such a drill press will know what a roll pin is.
    For the uneducated, a roll pin is simply a pin made up of a flat piece
    of material rolled into a cylinder, rather that a solid piece of
    material, usually steel.
    It is a two part device that each mounts to the tripod and the tripod
    hole on the camera, allwing one to quicly remove or replace the camera
    on the tripod. some happpen to conveniently get in the way of the
    battery door.
    Autobody filler is a plastic resin (comes as a putty with a separate
    tube of hardner agent; when you mix the two it starts a cemical reaction
    which hardens the putty) that cures hard. After it hardens, you can
    file/sand/grind/tool to the desired shape.
    Bondo is a brand name of auto body filler. It could also have been
    person also.
    Usenet is not one spot, and short term. A website of some sort is more
    permanent.

    They need charged more often, and/or you need more of them. On the plus
    side though, you can use the batteries in other things, and if need be,
    use standard alcaline AA cells, and for Li-IOon battery packs, you need
    to get costly OEM packs (but do typically get one with the device), or
    dodgy after market packs, and need the proprietary charger and/or
    charging cable.
    FWIW, my camera (nikin CP5200) has Li-Ion, and I have a "dodgy" spare
    pack, and have had no problems with it at all. If I go away, I just make
    sure I have both packs charged up.
     
  7. I think the day of NiMH cells is past. The Li ion packs are so much
    lighter, slimmer, and have so much more capacity (especially joules
    per kg) that you`d have to be a masochist to want to go back for most
    portable electronics. I think there are more-or-less standard sizes
    (eg. for cellphones) and usually if there`s a market there`s a 3rd
    party supplier (I have a couple spare packs for my DSLR and it will
    take 3 li primary cells in an emergency).
