This is the internal battery for the MacBook Air 11" 2011-2015 models, but this battery was originally shipped in the mid 2011 and mid 2012 models, with the lower 35Wh capacity.
The theoretical capacity of this battery when new was 4680mAh. This Grade-2 battery is holding between 75-90% of its original capacity, meaning this Grade-2 unit will have a full charge capacity between 3,510mAh and 4,212mAh.
Because of the weakness in the plastic frame around the battery, it is common for the screw mounts to become damaged on the upper right and upper left hand corner. This is not in every case, but it does not affect the function of the battery. This fault is not taken into account when grading this particular battery. Please contact us if you would like to confirm the physical condition of our current stock.
