Compatible MacBook models

This replacement battery fits the MacBook 13 inch A1331 unibody models produced from late 2009 through mid 2010. It matches the original A1342 specifications and replaces part numbers 661-5391 and 661-5585. The required installation tools and instructions are included in the package.

Sustained runtime behaviour

Premium lithium-polymer cells deliver longer runtime per charge and a longer overall service life compared with lower-quality alternatives. Each unit is individually tested before shipment to verify consistent output under continuous load. The cells are engineered to maintain stable voltage throughout the discharge cycle.

Upgrade context

The battery replaces a worn or failed original pack in the compatible MacBook 13 inch models. The jump is worth it when the existing battery no longer holds sufficient charge for mobile use or shows signs of swelling. It is not for users of other MacBook sizes, later unibody revisions or non-unibody designs.

The kit includes the special screwdriver required to open the unibody case, so no additional tools are needed beyond what ships with the battery.

Yes, the battery matches the original 661-5391 and 661-5585 specifications and is 100 % compatible with the factory charging circuit and power management.
