Yeah I've done it before, but the tricky part is getting the plastic
case of the battery apart. They can be ultrasonic welded, glued, or
clip-together. I've succeeded once in separating an ultrasonic
welded one by hitting it sharply all around the join with an
acrylic screwdriver handle to break the weld, then prying it apart
with a screwdriver wedged in the join. I don't think I'd discovered
that technique when I did the R31 battery, or it might have been
glued, so I had to try to try and cut it open with a dremmel, but I
couldn't get in far enough to some parts (also trying to avoid the
batteries which could catch fire if cut into) and ended up wrecking
it when I tried to pry it apart at one end enough to get to the
stuck bits on the other side where the connector was. Clip-together
ones usually need to be cut apart as well.

I've pulled apart more laptop batteries just to get the cells out,
trying to practice doing it without wrecking the case, and the
possibility of it all depends on how they're designed/assembled,
which varies a lot. Some are fairly easy, many fight you all the
way.
