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. -- __ __ #_ < |\| |< _#
