About this part
The Battery Management Unit Cover (Apple part number 923-04323) is a genuine Apple part that fits the MacBook Pro 13-inch M1 2020 and MacBook Pro 13-inch M2 2022. The battery powers the Mac away from the wall and also steadies power delivery under heavy load, so a worn cell affects performance too.
Before you order, match the model identifier on your Mac (Apple menu, About This Mac, System Report) to one of the identifiers listed for this part: MacBookPro17,1 and Mac14,7.
Signs the battery needs replacing
- "Service Recommended" in the battery status menu
- Short runtime, or the Mac shuts off at 20 to 40 percent
- A swollen battery lifting the trackpad or bottom case
- Slowdowns that disappear when the charger is plugged in
