Test post - new server, new ISP, probably sucks as much as the other
one, so here it goes. A repost.
I had some 9V alkalines that were only 7 or 8V, so I opened them up to
get the snap contacts. I found that of the 6 AAAA cells inside, only
one was bad, the other 5 had some life in them. So I decided to make
up a throwaway LED light, by soldering three AAAA cells, a resistor
and white LED, with some black electrical tape to hold them together.
I tried to solder a wire onto the top of one of the AAAA cells, but it
went PFFFT! and the top popped off and spat hot juice out. At which
time I said, maybe this isn't such a good idea, and went to the bench
and rigged up a battery holder. I cut out some springy metal
contacts and drilled some holes and mounted them to a piece of blank
PC board, and now it holds the single AAAA cell, and now I can run one
of my V boost circuits from it. But I've got better things to do than
make battery holders.
I Googled for "AAAA battery holder" and checked out pages and pages of
hits, but I still haven't been able to find an AAAA cell battery
holder. I've tried different combos of the words in "AAAA cell
battery holder", with and without the quotes, but I haven't been
successful. Mostly it comes back with "Nothing found. Did you mean
AAA cell holder?" I would even be satisfied with an AAAA to AAA cell
adapter. But the "AAAA AAA cell adapter" comes back nothing found.
When I do get hits, they're only for products that use the AAAA
cells.
I've been to Keystone Elect. http://www.keyelco.com/kec/pdfs/p12.pdf
and checked these contacts, but that's not what I want. What I'm
looking for is similar to one of these, but smaller.

I'm looking for a plastic holder with wire leads for 1, 2, 3 or 4 AAAA
cells. Am I asking too much?
UPDATE
------
I've been 'using up' the AAAA cells that I removed from the 9Vs, and
they are all popping open. The top (negative) with the button pops up
and sometimes lets the juice out. Sometims I can push the top back
down and get some more life out of the cell. One ran all night long,
and I got up this morning and it was still running the V boost circuit
but the LED was quite dim. So I measured the voltage and it was down
to 666 mV, still running the circuit but just barely.
So where, oh where have all the AAAA cell holders gone?
