  4. Plug in the power adapter and let your MacBook Air charge to 100% again.

Step 3: Check Battery Health

After replacing the battery, it is a good idea to check the health of your MacBook Air’s battery. You can do this by holding down the Option key and clicking on the battery icon in the menu bar. A drop-down menu will appear, showing the current condition of your battery.

Step 4: Dispose of the Old Battery Properly
