Throughout the following procedure, you'll be sliding thin plastic cards between the battery and rear case of the iPad, to separate the adhesive securing the battery in place. Be careful to keep the cards as flat as possible to avoid bending the battery, which may damage it and cause it to release dangerous chemicals.

Flip the iPad back over and insert a plastic card between the top left battery and the rear case.

If you encounter significant resistance, re-heat the iOpener and repeat the previous step to give the adhesive more time to soften.
