Hi, I'm considering purchasing a 13" MBP from the Apple Refurb Store. I was wondering if anyone else had purchased one of these refurbished yet? If so, have you noticed if the built-in battery had been replaced --- or were there a few cycles on it. I realize that Apple refurbs are as good as new - you just get a brown box instead or the original. However, I'm concerned that they might not be replacing the built-in battery which may have a number of charge cycles on it from its initial use. Thanks!
