Removal

Note: If you’ve already completed the removal steps, skip to reassembly.

1. Use a torque driver and the JCIS bit to remove the crosshead screw from the battery management unit (BMU) cowling. Set aside the screw.

   • Lift the end of the battery flex cable off the connector.

     

   • Lift the end of the microphone flex cable off the connector. Then gently peel the cable off the battery.

     

2. Use ESD-safe tweezers to remove five battery adhesive strips from the left battery cell.

   • Grasp the battery adhesive tab. Gently peel the adhesive tab away from the battery.

     • Warning: Don’t scrape or puncture the battery with the tweezers.

       

   • Twist the tab around the tweezers and pull up 1 inch until you see white adhesive strip on the tweezers.

     

   • Keep the tweezers close and parallel to the battery. Then pull the tweezers toward the top of the iPad and continue to twist and pull the adhesive until you’ve removed the entire strip. Repeat the process for the second, third, fourth, and fifth adhesive strip.

   • Caution: Don’t pull the adhesive strip against parts or screws.

     

   • Important

     • If the battery adhesive tab or strip breaks off and you can still see it, attempt to retrieve it with the tweezers. Wrap the tab or strip around the tweezers and continue to twist and pull the adhesive until you've removed the entire strip.

     • If a battery adhesive strip breaks and can't be retrieved, attempt to remove the battery by inserting the flat end of the black stick only into one of the insertion points as shown. Ensure that the black stick is inserted into a point where the battery strip has been fully removed.

       

   • Warning: If the battery is dented, punctured, or otherwise damaged, stop the repair. Don't remove the battery from the iPad. You can find a service option at support.apple.com/repair.

3. Repeat step 2 to remove five battery adhesive strips from the right battery cell.

   

4. After you’ve removed all 10 battery adhesive strips, slide the battery from the connector on the logic board. Then lift the battery out of the enclosure.

   

Reassembly

Warning

Inspect the enclosure for loose or extra screws and small parts, which may damage the battery and cause safety issues.

1. Use ethanol wipes or IPA wipes to remove all residual adhesive from the enclosure.

   • Caution: Don't use ethanol wipes or IPA wipes on any flex cables adhered to the enclosure.

     

2. Peel the clear release liner off the underside of the replacement battery.

   • Important: Don’t remove the protective cover from the top of the battery yet.

     

3. Hold the battery over the enclosure with the protective cover faceup. Align the edges of the battery with the logic board and speaker. Then lower the battery into the enclosure.

   

4. Press the end of the battery flex cable to the connector on the logic board. Then position the BMU cowling over the end of the flex cable.

   

5. Use the black torque driver and JCIS bit to install one new crosshead screw (452-10416) into the BMU cowling.

   

6. Move the adhesive activation roller back and forth over a battery adhesive strip 10 times to adhere the battery to the enclosure. Repeat the process for all the remaining battery adhesive strips.

   • Caution: Don't roll the adhesive activation roller over the BMU (shown in red).

     

7. Hold the edges of the protective cover. Pull the release tabs on the protective cover to remove it from the battery.

   

8. Press the end of the microphone flex cable onto the connector. Then gently press along the length of the flex cable to adhere it to the battery. Remove blue liners from the battery.
