Replacement battery for MacBook Pro 13 inch

This new lithium-ion battery replaces the A1322 and A1278 packs used in MacBook Pro 13 inch models from mid 2009 through mid 2012. It delivers 63.5Wh at 10.95V and follows a 1:1 design that matches the original dimensions and connector layout. The package includes the battery and free screwdrivers for installation.

Suits owners of listed mid 2009 to mid 2012

Buyers with a 2008 A1278 model cannot use this battery, as the specification explicitly excludes that year. Anyone needing a higher capacity than 63.5Wh or a different voltage should look at other options. Verify the exact model identifier and year before ordering.

Sustained discharge at rated voltage and capacity

The cell chemistry provides stable output at 10.95V across the 63.5Wh rating during typical workloads. Because the pack mirrors the original form factor, thermal behaviour inside the chassis remains consistent with the factory design. No performance figures beyond the rated voltage and capacity are supplied.
