Replacement battery does not fit.
I ordered a replacement battery from iFixIt, however, upon installing, I found the battery was not only more snug, but the cord comes out in such a spot where it becomes impossible to fit the ipod back in the case.
With some extreme finessing of the wires and headphone board, along with a sketchy snip of the blue plastic wrap (the plastic wrap, not the cell) in the wire corner I was able to fit it in. Leaving this post up so anyone else with this issue can possibly get help from it.
Ist dies eine gute Frage?
