MacBook Pro 15" 2009/2010 Replacement Battery

This lithium-polymer battery replaces the A1321 unit in MacBook Pro 15" models from mid 2009 and mid 2010. It delivers 77.5Wh at 10.95V across six cells. The package includes the battery and three screwdrivers for installation. It matches part numbers 661-5211, 661-5476, 020-6766-B and 020-6380-A.

Owners of Compatible 15" Models Only

This battery fits MacBook Pro 15" A1321 and A1286 units built in 2009 and 2010. It does not fit 2008 models or any 13" MacBook Pro. Buyers with later unibody or Retina designs should look elsewhere. The CE, RoHS and FCC certifications and built-in circuit protection address safety requirements.

Direct Swap with Included Tools

Installation uses the three supplied screwdrivers to remove the bottom case and disconnect the old pack. No soldering or extra cables are required. The 77.5Wh capacity restores original runtime. The battery sits in the existing bay, leaving all ports and expansion slots unchanged.
