About this part
The Bottom Case w/ Battery, Gold (Apple part number 661-02278) is a genuine Apple part that fits the MacBook (Retina, 12-inch, Early 2015). 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 the identifier listed for this part: MacBook8,1.
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
