Apple have posted details of a 15-inch battery exchange program. Apparently, â€œsome 15-inch MacBook Pro batteries supplied to Apple do not meet our high standards for battery performanceâ€� so you can check out your serial numbers and have them send another. Batteries with serial numbers beginning A1175 and ending U7SA, U7SB or U7SC are the ones to look out for.
They go on to say that â€œNo other MacBook Pro or MacBook batteries are part of this program.â€� and â€œNote: The affected batteries do not pose a safety risk. You may continue to use your current battery until a replacement arrives.â€�
