You can't open a MP2k pack in a way that will provide access to
all cell's terminals. At least not in a way that'd allow you to use it
afterwards.

Actually, I doubt that that what you describe is worth it. There is too
much chance of failure, even if you succeed you are from then on
working with a pack that is old and has been unusable once.
I'd do it that way with a pack that has cells that can't readily be bought
and that can't be replaced at a reasonable price, but the Newton's packs
don't fit in this category.
You'd need about 1/5 of the
time and no additional accessories if you just refurbished the pack with
new cells. And very little money. And the result these days would be
about 40% better than Apple's original.

reasonable price for others who don't own a soldering iron...)
