FAQ
- Q: Does this battery fit the MacBook Pro 15 Early 2011?
- A: No — the A1321 only fits the 2009 and 2010 A1286 models; the 2011–2012 A1286 models use the A1382 battery which has a different internal connector.
- Q: Is a screwdriver required for installation?
- A: Yes — A1286 Unibody MacBooks require removing the bottom case screws (Phillips #00) and the battery tri-wing screws; we recommend following our detailed online tutorial for a safe swap.
