Original Apple service spare internal battery for the mid-2009 (SD-slot) and mid-2010 models of 15" Unibody MacBook Pro. The original Full Charge Capacity of this battery was 6667MAh.
Please note that this battery is held in place by 3 x anti-tamper Torx Plus 6 screws which are a 5-pointed star rather than the normal 6 pointed torx.
There are 2 revisions of this battery, but they are completely interchangeable. The lower 73Wh version was made for the 2009/SD model, and the 77.5Wh version was made for the 2010 model, so has a slightly higher charge capacity
