Grab both pull–tab ends labeled with an A and pull up on the orange adhesive strip to lift the battery out of its recess and swing it up to an upright position.

Although these adhesive tabs are supposed to make the battery removal easier, they may require some force. In case you're having trouble removing the battery, you can apply a heated iOpener to the center of the display to loosen the adhesive underneath.

Peel the battery off the remaining adhesive.

Remove the battery.

Do not reinstall a damaged or deformed battery, as doing so is a potential safety hazard.

During reassembly, temporarily reconnect the battery to the motherboard to help align it correctly. Disconnect the battery after it is seated.
