After reading some posts here and on other sites regarding the rebuilding of iBook batteries (and laptop batteries in general), I got the sense that rebuilding my Clamshell battery would be relatively painless. This impression was further supported by my investigation of an "ice" iBook battery (from a G3 700MHz model) that I happened to have...after opening it up to see what was inside, it looked like a straightforward enough task. I just purchased new LiIon cells...with solder tabs, even! (wanting to make this as effortless as possible)...only to be surprised and discouraged once I opened up my Clamshell battery pack. Everything is tied down/glued/silconed into place extremely well, with little to no access to the battery terminals. I am able to sneak a peak at the terminals, though, and was ever more disheartened at the sight of a welded/soldered strip of metal snaking its way around the cells, attaching itself to various terminals in the 8 pack to create the 14.4 V (4 in series, 2 groups in parallel). Bottom line: this does not look fun. Has anyone ever done LiIon cell replacement in the Clamshell configuration? Tell me I don't have to me a welding expert, please. I'm a mechanical engineer, so I'm not afraid of a bit of soldering, but this just doesn't seem like a project for even the brave of heart. Thoughts? Tips? I guess I'm looking for people's experiences and anecdotes. Post 'em if ya got 'em! Applefan1997, hope I hear from you (you were the only post I found stating that you had actually done this before). Thanks!
