I had a similar situation once. I did manage to get them apart; seemTrudeau said:I have a rechargable drill that has some batteries that are bad. Id like to
replace them. Inside the battery pack are 10 or so rechargable batteries.
The problem is that they are connected together (in series) with a tang of
metal that is spot welded to each battery connecting them together. I dont
think I can un soder this, as its not really sodered. Its spot welded. I
could cut the tang I suppose but dont know How I would connect this up
again. And do it in such a way that will let me fit it back into the drill
pack it comes from. (Obviously I want to replace some of the faulty
to recall 'tearing' or cutting. Obviously need to retain as much of
each tag as possible when cutting. Then I was able to place solder on
the tags. Position solder spots so that you can fold up afterwards.
Also place solder on opposite side on one tag, so that when (large)
solder tip applied it will melt solder on other side of tag, against
which you've pressed the next battery's tag. If there really is
insufficient tag left after cutting to enable 're-folding', solder on
some heavy wire or tin strip.
Easier to do than describe <g>.
