I also have some dead iBook clamshell batteries. I have tried to figure out how to take them apart, but so far no luck. I peeled the stickers off each side and I can see the cells, but attempts at loosening the snaps or prying the case apart have failed. Obviously, I could use the dremel and cut the thing open, but I'd like to preserve the casing. ANy suggestiongs on how to disassemble them?
