Questions about this item

Which MacBook Pro 13 models does the 63.5Wh 10.95V battery support?

It fits MacBook Pro 13 models from 2009 through 2012, including part numbers 661-5557, 661-5229, and all MC and MB variants listed, but not the 2008 A1278 model.

What physical mounting does the battery require inside the MacBook Pro 13?

The pack uses the original Apple screw-hole pattern for the A1278/A1322 chassis; you reuse the existing tri-wing and Phillips screws that secure the factory battery.

What installation step do people often miss when fitting this battery?

After seating the connector, you must press the battery firmly into the recess so the adhesive pads bond before you reinstall the lower case screws.
