    • Use the edge of a spudger to pry the battery connector upwards from its socket on the logic board.

    • It is useful to pry upward on both short sides of the connector to "walk" it out of its socket. Be careful with the corners of the connectors, they can be easily broken off.

    • Do not remove the label from the battery.

    • Use the attached plastic pull tab to remove the battery 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.

Conclusion

To reassemble your device, follow these instructions in reverse order.

Take your e-waste to an R2 or e-Stewards certified recycler.

I thought these batteries couldn't be replaced.

These batteries are built to the same spec as OEM (Apple)

They are just not "user friendly" to replace like most devices are, the price we pay for pretty devices.

This guide is excellent and now I know I need 1 more tool before I do this myself. I need that tri-wing screwdriver.

Anyone know of any batteries with a larger capacity that could fit this?

It seems that there are no true larger capacity batteries for this Macbook. Ones that claim higher capacity are usually of dubious quality.

Clear, well written instructions, thank you! (But yes, a line about take off shoes and socks and ground yourself is helpful. )
