Introduction

Follow this guide to safely remove and replace the battery from your 2019 MacBook Air.

To minimize risk of damage, turn on your MacBook and allow the battery to fully discharge before starting this procedure. A charged lithium-ion battery can be very dangerous if accidentally punctured. If your battery looks puffy or swollen, take extra precautions.

  1. MacBook Air 13" Retina Display 2019 Battery Replacement, Remove the screws securing the lower case: step 1, image 1 of 1
    • Before starting this procedure, you should disable your Mac's Auto Boot feature. Auto Boot powers on your Mac when you open the lid, and may be accidentally triggered during disassembly. Use this guide to disable Auto Boot.

    • If your MacBook is running Big Sur v11.1 or later, disabling Auto Boot may not work. You can proceed normally, but make sure to disconnect the battery as soon as you're inside.

    • Completely power off and unplug your MacBook Air before you start. Close the display and flip the entire laptop upside-down.

    • Use a P5 driver to remove the following screws:

    • Two 7.9 mm screws

    • Two 7.1 mm screws

    • Six 2.6 mm screws

  2. MacBook Air 13" Retina Display 2019 Battery Replacement, Remove the lower case: step 2, image 1 of 1

    • Repeat the previous two steps to remove the three adhesive strips on the other side of the battery.

    • If any of the adhesive strips broke, you can use high-concentration (>90%) isopropyl alcohol to help remove them:

    • Carefully drip isopropyl alcohol along either edge of the battery, in the recessed part of the upper case, where the adhesive pull tabs were.

    • Applying too much alcohol or applying it outside of the wells in the case where the adhesive sits risks damaging other components.

    • Let the alcohol soak into the adhesive for a minute or two.

    • Use opening picks to gently pry the battery away from the upper case.

  34. MacBook Air 13" Retina Display 2019 Battery Replacement, Remove the battery: step 34, image 1 of 1
    • Remove the battery.

    • Calibrate your newly installed battery: charge it to 100%, and keep charging it for at least 2 more hours. Unplug and use it normally to drain the battery. When you see the low battery warning, save your work, and keep your laptop on until it goes to sleep due to low battery. Wait at least 5 hours, then charge your laptop uninterrupted to 100%.

    • If you notice any unusual behavior or problems after installing your new battery, you may need to reset your MacBook's SMC.

Conclusion

Compare your new replacement part to the original part—you may need to transfer remaining components or remove adhesive backings from the new part before installing.

To reassemble your device, follow the above steps in reverse order.

Any issues with replacing the speakers without an adhesive. I see they shift around a little bit, but perhaps with the back cover on they stay in place. Any advise on this?
