Replacing the battery in your MacBook Pro 14" M1 Pro/Max A2442 (2021)
A MacBook battery lasts a long time, but not forever. Apple rates it for about a thousand charge cycles; after that it holds noticeably less charge. You notice it when your MacBook needs the charger by mid-afternoon, shuts down while it still seems to have some percent left, or suddenly slows down on battery.
This MacBook Pro charges through MagSafe 3 and supports fast charging, which is convenient but also works the battery harder. After a few years of heavy use, especially video work or living on the charger, we regularly see this model drop below the threshold.
How to check your battery
- Open System Settings → Battery and look at the battery condition. If it says "Service recommended", it is time.
- You find the cycle count under System Information → Power.
- Is the trackpad bulging, does the lid no longer close flat, or does the machine rock on the table? Then the battery has swollen. Stop charging and bring it in: a swollen battery presses on the parts around it.
