Used original Apple battery taken from a disassembled new 15" Unibody Macbook. These batteries are not classed as new because some have slight cosmetic damage caused by careless handling. They are fully working and because they are completely enclosed within the casing of the MacBook Pro, any cosmetic marks will not be visible. Originally this battery would have had a full charge capacity of 5400mAh. This battery is between 2700mAh and 4050mAh.
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)
10.8V, 50Wh
Condition : Grade-3
