Replacement Battery for A1286 Mid 2009-2010

This new FOCUSTEC A1321 lithium-ion battery replaces the original pack in MacBook Pro 15-inch models A1286 from Mid 2009 and Mid 2010. It delivers 73 Wh at 10.95 V and arrives at 100% health with overcharge and discharge protection built in.

Suits Mid 2009-2010 owners; not for 2011-2012

The cell fits part numbers A1321, 661-5211, 661-5476 and 661-5844 and matches MC118, MB985 and MB986 series machines. Buyers with Late 2011 or Mid 2012 A1286 units cannot use this pack and must source a different version.

Key spec: 73 Wh at 10.95 V

Capacity and voltage determine whether the battery will run your Mid 2009 or Mid 2010 MacBook Pro correctly. Verify your model year before ordering; the 2011 and 2012 revisions require a different electrical profile.

Questions about this item

What MacBook Pro 15" model numbers does the A1321 battery fit?

The A1321 fits Mid 2009 and Mid 2010 A1286 models including MC118, MB985, MB986, MC371, MC372 and MC373 part numbers. It does not fit 2011 or 2012 versions.

Which screw type secures the battery inside the A1286 unibody, and what step is often missed?

The battery uses tri-wing screws; the step often missed is disconnecting the trackpad flex cable before lifting the old battery to avoid tearing the ribbon.

After how many charge cycles should the A1321 be replaced?

The cell is rated for more than 500 full recharge cycles; plan replacement once cycle count approaches that figure or when run-time drops noticeably.
