63.5 Wh 13-inch MacBook Pro battery

This 10.95 V lithium-polymer pack replaces the original A1322 unit in 13-inch MacBook Pro models from 2009 through 2012. It fits machines identified as MacBookPro 5,5, 7,1, 8,1 and 9,2 with EMC numbers 2326, 2351, 2419 and 2554.

Installation with included screwdrivers

The box supplies the battery plus a set of screwdrivers so the bottom case can be removed and the old pack swapped without sourcing extra tools. The main risk is damaging the fragile battery connector or stripping the tiny case screws if excessive force is used.

63.5 Wh capacity and 500-cycle rating

At 63.5 Wh the cell delivers a full day of typical office work on a fresh charge, but runtime drops noticeably under sustained heavy loads such as video rendering. The manufacturer rates the pack for up to 500 recharge cycles before capacity falls below useful levels.
