Lift and remove the battery.

If there's any alcohol solution remaining in the device, carefully wipe it off or allow it to air dry before installing your new battery.

Don't reuse the battery after it has been removed, as doing so is a potential safety hazard. Replace it with a new battery.

To install a new battery:

Remove the old adhesive and residue from the battery well.

If your replacement battery doesn't come with replacement adhesive, apply stretch release adhesive strips, double sided adhesive tape, or pre-cut adhesive in the iPad's battery well.

Peel away any tape liners to expose the adhesive.

Lay the battery on the adhesive and press firmly.
