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.

Insert a plastic card under the battery from the Lightning cable connector end of the iPad.

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