This is the internal battery for the MacBook Pro 17" mid 2009 and mid 2010 models.
Battery Specs:
•7.3Vdc
•95Whr
•13,000mAh
The theoretical capacity of this battery when new was 13,000mAh. 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 9,750mAh and 11,700mAh.
Please note:
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)
