简介
使用本指南从 2020 年初的 MacBook Air 中安全地卸下和更换电池。
为了最大程度地降低损坏风险，请在开始此过程之前打开 MacBook 并让电池完全放电。 充电的锂离子电池如果被意外刺穿会非常危险。 如果你的电池看起来浮肿或膨胀，请采取额外的预防措施。
此过程包括卸下两个扬声器。你将需要新的粘合剂来正确地重新安装扬声器以避免过度振动或嘎嘎声。
你所需要的
-
-
如果你的 MacBook 运行的是 Big Sur v11.1 或更高版本，则禁用自动启动可能不起作用。你可以正常进行，但请确保在你进入后立即断开电池连接。
-
使用 P5 螺丝刀卸下以下螺丝：
-
两颗 7.9 毫米螺丝
-
两颗 7.1 毫米螺丝
-
六颗 2.6 毫米螺丝
-
-
-
使用一把镊子剥开扬声器拉伸剥离粘合剂上的黑色拉片，直到你可以用手指抓住它。
-
抓住胶带的拉条，然后将胶带从扬声器下方慢慢拉出。
-
拉动胶带，直到它从扬声器下方脱离。
-
对扬声器加热以软化下面的粘合剂。
-
小心地在扬声器下方滑动撬棒或撬片以分离粘合剂。

抓住胶带的拉条，然后将胶带从扬声器下方慢慢拉出。
-
拉动胶带，直到它从扬声器下方脱离。
-
对扬声器加热以软化下面的粘合剂。
-
小心地在扬声器下方滑动撬棒或撬片以分离粘合剂。

-
卸下电池组件。
-
如果你要安装新电池，请遵循校准程序：
-
将其充电至 100%，并继续充电至少 2 小时。
-
拔下插头并正常使用以耗尽电池电量。
-
当你看到电池电量不足警告时，请保存你的工作，并让你的笔记本电脑一直开机，直到它因电池电量不足而进入睡眠状态。
-
等待至少 5 小时，然后不间断地为您的笔记本电脑充电至 100%。
-
将你的新更换零件与原始零件进行比较——你可能需要在安装前转移剩余的组件或去除新零件上的背胶。
要重新组装你的设备，请按逆序执行上述步骤。
将你的电子垃圾送到 R2 或 e-Stewards 认证回收商。

Any users brave enough to try this battery replacement on their own? I’m looking at it to get myself prepared for what is expected in the future. I can see myself keeping this M1 MBA for a long time so replacing the battery is going to be in my future.
Best of luck to anyone out there trying this! It doesn’t look particularly difficult.
These new MacBook Airs definitely have a simpler battery replacement procedure than other MacBook models. Whenever you need the M1 MacBook Air battery replacement guide, you can find it here! Have fun fixing!
This one is pretty easy - easier than other laptop battery replacements I've done. The hardest bit is getting the speakers out, you definitely need a hot air gun or hairdryer.
Try it! What could possibly go wrong?
I have a 2020 MacBook air that got water damage. It was still working until the battery died but then wouldn't charge. I've replaced the screen as it had water marks and the battery looked like it had shorted out (there was blisters on it). So I replaced the battery too. But it's still not turning on after charging it overnight. I've doubled checked everything is connected inside. Is there's anything I need to reset or check to get it to charge up and turn on?
Ryan, you could look into trying a new USB-C board, because if that doesn't function due to liquid damage then the new battery may not charge. Especially because you said:
It was still working until the battery died but then wouldn't charge.
Best of luck in your repair!
