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.

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.
