Introduction
Use this guide to replace an aging battery. If your battery is swollen, take appropriate precautions.
What you need
-
-
Remove the following ten screws securing the lower case to the upper case:
-
Three 13.5 mm (14.1 mm) Phillips screws.
-
Seven 3 mm Phillips screws.
-

-
Using both hands, lift the lower case near the vent to pop it off two clips securing it to the upper case.
-
Remove the lower case and set it aside.
-
-
-
-
Remove the two 7.4 mm Tri-point screws securing the battery to the upper case.

Note: For certain repairs (e.g. hard drive), removing the battery is not necessary but it prevents any accidental shorting of electronics on the motherboard. If you do not remove the battery, please be careful as parts of the motherboard might be electrified.

Lift the battery by its plastic pull tab and slide it away from the long edge of the upper case.

Tilt the battery away from the logic board enough to access the battery cable connector.

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.
