This is the internal battery for the MacBook Pro 15" Late 2011 and Mid 2012 models. This is not compatible with the 2009 or 2010 machines due to having a different connector design.
Because of the weakness in the plastic frame around the battery screw mounts, it is common for these mounts to become damaged. 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.
The theoretical capacity of this battery when new was 7,077mAh. This Grade-1 battery is holding between 90-100% of its original capacity, meaning this Grade-1 unit will have a full charge capacity of at least 6,369mAh.
Apple introduced an OS function that checks the status of the battery, so some of these graded batteries will have a status saying 'Service Battery' or 'Replace Soon'. This has no connection to the overall charge capacity of the battery and how long it lasts however. All these batteries have been fully tested and graded according to their full charge capacity and cycle count and are graded using the details stated above, so the message has no relevance to these batteries and can be ignored.(Unfortunately there is no way of overriding this, but resetting the SMC can sometimes remedy this fault)
