This is a used 3-Grade battery for the 13" Unibody Macbook. The battery is in excellent condition and holding between 50-75% of its original capacity. The original capacity was 4500mAh. This battery will be between 3375mAh and 2250mAh.
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)
