Introduction
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.

- To ensure that everything is de-energized and won’t turn on while you’re working, it is recommended that you disconnect the battery.
- Grab the clear plastic pull tab attached to the battery connector and pull it parallel to the board toward the front edge of the Air.
- Do not lift upward on the connector as you disconnect it or you risk damage to the connector socket.

Step 5
- When handling the battery, avoid squeezing or touching the four exposed lithium polymer cells.
- Lift the battery from its edge nearest the logic board and remove it from the upper case.
- Your replacement battery may arrive with a plastic film lightly adhered to the top surface. Remove this film when you install the battery. However, if the film is glued on and is difficult to remove, you can leave the film in place.
- If you’re installing a new battery, you should calibrate it after installation:
- Charge it to 100%, and then keep charging it for at least 2 more hours. Then, 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.

Do I have to allow the battery to completely discharge and then recharge after replacement? One site said that was appropriate way to do it.
Jeff Suovanen - Jul 28, 2017
Yes, for best results you should calibrate your battery by draining it completely and then charging it uninterrupted to 100%. Once it hits 100%, leave it plugged in for a couple more hours. Then drain it again until it shuts off automatically (make sure it doesn’t go to sleep). After that, charge it up and use it normally.

But thats a myth … if I’m not wrong, only nickel battery can be calibrated, the os-systems of theses days take care of it, like with all smartphones nowadays.

@mrgrdn You might be thinking of memory effect. Calibration is still very much a thing and quite important, particularly on a new battery. Here’s some reading if you are curious!
