Installing the battery

1. You need to put on two new adhesive strips to attach the battery to the back cover. The adhesive strips have to be positioned so the two tips end just before the flexible flat volume cable, and the strips are centered between the logic board and the outer wall opposite it.
2. Use your fingers to firmly press the adhesive strips onto the back cover so they won’t get stuck on the red film when you pull it off.
3. Remove the red protective film.
4. Position the battery so that it’s centered on the adhesive strips. You can also use the black end of the adhesive strips to orient yourself. The battery has to line up exactly with the white adhesive strips. Make sure there’s enough space between the battery and the logic board for the battery connection.
5. Fold over the black end in the middle.
