Oztules,
On these particular cells they had a transparent green coating
and you could see the silver streak (back side), at the factory,
they must have left a spot on either side uncoated (pos. and neg.)
so they could solder to the silver streak.....I think the wire came
loose along with the solder.....and the silver streak ! so it was
probably a lost cause....more trouble than it would be worth.
I was just practicing anyway....
No problem with the other three, the solder spots with the broken
wires embedded....I soldered the ribbons just like you said.....
A touch of flux on the solder spot then the tin on top and the solder
pen on top....easy enough.....have a cheap pencil soldering copper,
but I regulate the heat with an in line dimmer switch.
So I have about a dozen or so others that I can practice on.
Do you think that I could really make enough sets of these to be practical?
I was thinking of doing this on a small scale and gradually accumulating
them consisting of 5 or even 1 watt units.
I'm thinking of real conservative like $5.....$10
