Step-by-step

1. 1

   Power down the Fire tablet

   1 min

   Press and hold the power button until the shutdown prompt appears on screen. Tap 'Power Off' and wait for the display to turn completely dark.

2. 2

   Insert opening tool near the power button

   2 min

   Insert a thin plastic opening tool into the seam between the outer plastic shell and the screen bezel near the power button. Work carefully to avoid scratching the plastic bezel.

3. 3

   Unclip the top edge

   2 min

   Slide a plastic opening pick along the top edge to disengage the internal plastic retention clips. You will hear a series of faint popping sounds as clips release.

4. 4

   Pry open the right side

   2 min

   Continue sliding the pick down the right edge of the tablet. Twist the tool gently to release each clip along the perimeter.

5. 5

   Unclip the bottom edge

   2 min

   Move the pick along the bottom edge, separating the rear casing from the display frame. Ensure all lower clips pop loose.

6. 6

   Release the left side clips

   2 min

   Slide the tool up the left edge toward the top corner. Verify that all plastic clips around the outer rim are disconnected.

7. 7

   Remove the rear plastic cover

   1 min

   Lift the rear cover straight up off the tablet assembly. Set the rear shell aside in a safe workspace area.

8. 8

   Peel back electrical tape over battery connector

   2 min

   Locate the battery flex cable attached to the top of the mainboard. Use tweezers to carefully peel back the strip of black kapton tape covering the socket.

9. 9

   Disconnect the battery cable

   2 min

   Place the flat edge of a spudger beneath the battery connector plug. Pry straight up to pop the connector off the motherboard socket.

10. 10

    Apply isopropyl alcohol around battery edges

    3 min

    Apply a few drops of high-concentration isopropyl alcohol along the left and right edges of the battery. Allow 1-2 minutes for the alcohol to soften the underlying glue.

11. 11

    Insert plastic pry card under battery

    3 min

    Slide a flat plastic card or wide spudger under the left side of the battery cell. Keep the tool flat against the frame to avoid puncturing the battery pouch.

12. 12

    Lever the battery out of the frame

    3 min

    Gently lift the pry card upward to break the adhesive bond holding the battery to the metal midframe. Work slowly across the entire underside.

13. 13

    Lift and discard old battery

    1 min

    Remove the old battery from the tablet chassis. Set it aside for proper lithium-ion battery recycling.

14. 14

    Clean adhesive residue from midframe

    2 min

    Wipe the battery bay using a lint-free cloth dampened with isopropyl alcohol. Ensure the frame surface is clean and dry before applying new adhesive.

    Peel the backing off new pre-cut battery adhesive strips and lay them into the recessed battery compartment. Press firmly to secure adhesive to the frame.

16. 16

    Position replacement battery

    2 min

    Remove the protective film from the adhesive strips. Align the new battery in the frame bay, ensuring the flex cable reaches the motherboard connector.

17. 17

    Press replacement battery into place

    1 min

    Press down gently on the surface of the battery to secure it to the fresh adhesive strips. Do not apply excessive pressure directly to the cell.

18. 18

    2 min

    Align the battery cable plug directly over its motherboard socket. Press down firmly until it snaps securely into place.

19. 19

    Reapply black protective tape

    1 min

    Place the black tape back over the battery cable connector to protect it from vibration and accidental disconnection.

    Align rear cover onto chassis

    1 min

    Position the rear cover back over the display assembly, aligning the camera cutout and button openings.

21. 21

    Snap rear cover clips into place
