Problem is I am not at all sure how to secure a conductor from "plus" to
"minus" with the cells to make a strong and long-lasting series connection.
Is there some kind of conductive adhesive or conductive film that can be
used for this application? Larry, where are you when we need you (weak
humor)?

Conductive adhesive does not work for these currents.

Get them from a manufacturer's distributor - they will weld them with
strips in any shape you like, or even have them in your desired shape.
By far the best option.

Our local stores can take apart many, but not all, battery packs and
replace the cells with new, even improved ones. My old Standard marine
walkie has 2.8AH Ni-mh cells replacing the old .6AH Ni-Cds. Batteries Plus
has the spot welding equipment right in the stores to safely weld the
straps onto the cells without damaging either, same as the manufacturer of
the pack.

The best rebuilders hardly make a scratch breaking open the plastic welds,
but, of course, there's no guarantee. As he's breaking something that's
patently worthless, there's no risk. If you worry about him getting it
apart, do what I do, take the pack apart, YOURSELF, and carry the guts of
it into the store, then reseal the pack yourself.

That 2.8AH power beast costs about half what any Waste Marine would want
for a 600maH pack in a bubble pack. Having over 4 times the capacity of
the original is no-extra-charge...(c;

This is how the tabs should be put on the cells. The holes are for
soldering AWAY FROM the cells so as not to heat them. They are for wires.

When someone makes a pack with the proper welding machine, there is no
soldering except for the output wires, which is the proper way to make a
pack.

Umm, I don't have one of those...

Precisely why you need to seek out a battery shop that does....

Maybe in a perfect world, but Marc Heusser said I'm also free to solder them
if I like. (I thought it was quite the magnanimous gesture.)

I think you need to move up to the next larger sized tin foil hat. This
one is
too tight.

Bad, bad advice.
