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

Step 3

              Battery Connector

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.

Two 5.2 mm T5 Torx screws
One 6 mm T5 Torx screw
Two 2.6 mm T5 Torx screws

Step 5

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.
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. Next, 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.

How many hours can I expect iFixit’s replacement battery to last? [for the 2015 MacBook Air 11”]

Andrew Aldis - Oct 9, 2019

Hello. I bought your replacement battery and replacing was easy but I had to do it a second time because the new battery seems thicker and affected the trackpad operation. I’ve tried a second time and it looks like the trackpad is lifting on the right hand side and it doesn’t click properly. Any idea whether this is something I can sort out?

Thanks

Jeff Suovanen - Oct 16, 2019

@carlyleroad It should not be any thicker and should not affect trackpad operation at all if installed correctly. Double check to make sure you ordered the right part for your specific model. If you think you received a defective part, contact iFixit customer support and they can help sort things out. Good luck!
