[EMAIL PROTECTED] has a website with some photos. I've done a couple,
both the Type III as well as Type I batts. I buy my cells from vendors at
some of the amateur radio shows and pay around US$3 each. Make sure you get
"tab" batteries, soldering to a NimH cell is not good. The Type III uses
4/5ths "A" cells (shorter and fatter than your typical "AA" cell) and the
Type I uses the standard "AA" cells. You will need 10 of whatever cell is
needed.
I normally open the pack with a small motorised saw called a Dremel tool. I
cut the weld out to allow for re-gluing and clamping when finished. Some
packs may be opened with a knife and some time....but be careful, it is tough
to type when you are missing fingers!
When I have the pack open, I then remove the "guts" and separate the sensors
and contacts from the batteries. The new cells are assembled (soldered via
the tabs) in rows to allow placement into the "frame" (or shell) of the pack.
The contacts are attached to the front cells (same placement as the
original) and then I connect the rows together once I have everything
well-located in the frame (don't forget to make sure that the top piece will
fit the battery....there is very little room for error as the battery fits
tight in the Duo).
When assembled, you will have 4 rows of 3 cells connected in series. I
normally cheat and use a piece of insulated braid to connect the back row to
the contacts (in the original, there is a flat piece of metal "tabbing" which
connects the last cell to the contact....but I rarely can reuse that
piece....you will understand once you disassemble your first unit). MAKE
SURE that there are no short circuits!!
Jens, if you haven't a soldering iron (low wattage) or haven't a friend who
is a "tinkerer" with electronics who can help, you may want to look for a
standard Apple battery. If you are a "tinkerer," go for it!! I redo all my
battery packs....but then again, I'm Scottish (insert obligatory "Tight
Scots" joke here).
One small comment....if you have any Type I dead batteries, I recently
discovered that some of the stock 9.6V and 12V Radio Control battery packs
are just the right size to insert into the Type I shell/frame (natch, you
will need to add a row to the 9.6V packs, but I had found them cheap at a
surplus store).
Hope this gets you started, I'm certain some of the other folks will jump in
with more hints, too. This is a great list, lots of good folks. Enjoy!!
