Watch out for the Hold Button wire!
I don't know where else to put this...BTW-overall awesome instrucrtions for how to replace an Ipod battery!
BUT there should be a warning in the manual for the 5th Gen iPod video (classic) at the very end to WATCH OUT for the hold button wire when you are prying the battery adhesive loose.
My repair went fine, but I broke that wire and now I have no hold. It will probably cost me more for a repair on that wire than I saved doing the battery replacement myself. Oh well.
Is this a good question?
