Use a pair of tweezers to peel off the remaining adhesive strip parts.

Clean the glued areas with isopropyl alcohol and a lint-free cloth before installing a new battery to ensure the new battery fits and the adhesive bonds correctly.

If your new battery doesn't come with adhesive pre-applied, secure it with pre-cut adhesive or double-sided adhesive tape.

In order to position it correctly, apply the new adhesive into the iPad at the places where the old adhesive strips were located, not directly onto the battery. Press the new battery firmly into place for 5-10 seconds.
