Thanks for the tips, much appreciated.
As well as the cheap / weak plastic lugs I am sure
the pressure of the bent metal battery contacts has
a lot to do with it, a friends Casio has spring contacts
which aren't so strong and the flap shuts easily.

I am not sure what you are referring to about bent metal contacts. At
least in my situation that wasn't the case. Closely examining the
situation when my door broke I found that everything was normal except the
notch on the cameras frame where the latch catches. That very small
plastic catch had snapped and the door simply would no longer lock in
place. My understanding of the problem was that the 990 was designed where
the batteries (because of the contacts and springs inside the compartment)
were under so much pressure that the design of the catch was just not
sufficient enough to hold the door over time. That is one reason why I
figured that the metal plate was a better solution. I did try to glue the
catch and looked at the fiberglass solution but that seemed way to
intricate to me. You would need to take a knife and shred the glass fibers
and lay them in place with some cement... Then there was the possibility
that it would just happen again. The problem being that the pressure and
stress is still on that catch. In fact the metal plate solution might be
worth consideration for those who haven't even had their doors break yet.
Properly built it will actually take some of that pressure and stress off
of the catch and may also prevent what happened to me. At the least, it
will prevent the door popping open on you during a shoot and can help you
keep going. I was out observing with my telescope. It was a very cold
night when the camera started to go on and off and act funny. A couple
moments later I heard a rattling sound as the door FLEW open throwing all
the batteries into the darkness. I suppose the cold weather might have
played some roll in the latch breaking at that time. The plastic might
have gotten a little too cold and brittle. Incidentally I have also seen
similar problems mentioned with the 950 as well. I don't know if other
Nikon cameras are also defective in this way.

US Fix.
OK, now that few ideas have rolled into the equation, lets look at a
different way to go about this.
If you fix the camera with the glue and the tabs and screws and what not
you
still risk the same problem again, so why bother. If you alter it and
decide
at a later date to repair it at Nikon (the only guys with parts for these
things, your "screwed" as the bill will be larger for the other parts now
being modified not working.
I had this problem with the 950 and the 990. The battery cover is a weak
spot because of the pressure of the springs.
So, I took some silicon cement and closed the doors with a dab or two.
Enough to close and easy enough to get off at a later date when they get
repaired.
I use my Jacobs battery packs for the two cameras and never went back to
the
batteries. I also use the same pack on my flashes, my bikes for night
halogens, my GPS's and my field radios, two power remote radios for SARs.
The plans are free and the parts are very easily available. Just go to
my
website and look under powerpacks. They are about four to six times more
powerful than the cheap stuff in the yellow packages. Read my website for
other battery answers....
International Fix. (FAQ)
Plan A:
They do sell the Yuasa 4 amp- six volt batteries in at MDS in the UK . And
I'm looking for a 6 V charger that operates on your voltage.
Plan B:
I suppose you still have the AA batteries. In the UK you must have a Radio
Shack or similar type store.
They make a 6 cell AA holder for the NiMH.
Get two you want to put them in parallel so you get twice the longevity,
otherwise any powerpack is a waste of money.
Why six cells, simple 4 Nimh 0nly equal 4.8 volts. They don't make a five
holder. So you go six.
Five cells plus a dummy = 6 Volts ( Dummy cells are fake batteries,
pictures on my site)
The AC port on the Nikons take six volts.
Plan C:
Now for the 995 Nikon user. Six cells and you have 7.2 enough for a Nikon
995. Only the charger is 8.4
995 user can also use packs made for the RC cars we call them here.....
Why two packs together? Simple....twice the longevity. If your batteries
are 1800 NiMH x 2= 3600mah pack.
Now you know how the big guys make claims about their super packs.....no
brainer..
