简介

Use this guide to replace the battery to restore freedom from your charger to your MacBook Air.

Note: If there is a thin plastic film on your replacement battery, do not attempt to remove it. It is glued on and protects the battery pack while it is inside the MacBook.

    • Shut down and close your computer. Lay it on a soft surface top-side down.

    • Remove the following ten screws:

      • Two 8 mm 5-point Pentalobe screws

      • Eight 2.5 mm 5-point Pentalobe screws

    • The special screwdriver needed to remove the 5-point Pentalobe screws can be found here.

    When you say:

    Remove the following ten screws:

    Two 8 mm 5-point Pentalobe screws

    Eight 2.5 mm 5-point Pentalobe screws

    Do the 8mm & 2.5mm dimensions refer to the LENGTH of those screws, or the size of the pentalobe? That is, are there other sizes of pentalobe drivers like there are for hex, phillips and torx? When only one dimension is provided, it is usually the socket/driver size, not the screw length, maybe since the length cannot be seen when the screw is installed.

    Can I suggest that you clarify your instructions so folks are confident they are only in need of _one_ pentalobe driver?

    Nerdily yours,

    The 8mm and 2.5mm are the length of the screws. One pentalobe P5 screwdriver suffices for all the screws (P5 is implicitly the size of the pentalobe screw heads).

    I sourced all the parts from ifixit, plus a magnetic project mat which I found to be very useful for organising the teardown and reassembly.

    Keep the 2.5mm tiny screws away from the MagSafe connector as they will be attracted and sucked in to the magnet.

  1. Wedge your fingers between the display and the lower case and pull upward to pop the lower case off the Air.

    • In this step you will disconnect the battery to help avoid shorting out any components during service.

    • Use the flat end of a spudger to pry both short sides of the battery connector upward to disconnect it from its socket on the logic board.

    • Bend the battery cable slightly away from the logic board so the connector will not accidentally bend back and make contact with its socket.

    When reassembling the connector wire needs to be bent to fit.

    • Remove the following five screws securing the battery to the upper case:

      • Two 5.2 mm T5 Torx screws

      • One 6 mm T5 Torx screw

      • Two 2.6 mm T5 Torx screws

    Be carful with the torque when reassembling, these screws seem able to go a little too far and crack through the plastic of the battery.

    • When handling the battery, avoid squeezing or touching the six exposed lithium polymer cells.

    • Lift the battery from its edge nearest the logic board and remove it from the upper case.

    I’m not an expert and cannot provide advice about this, but I think that it might be important to recalibrate the energy saving settings after the battery has been replaced.

Surprisingly easy for Apple.

Pretty easy; good instructions. Had to fiddle a bit to get the battery back in with a good connection because the battery cable was stiff.

Battery passed Tech Tool Pro’s check.
