以下是官方公告(英文):We recently discovered that some 15-inch MacBook Pro batteries supplied to Apple do not meet our high standards for battery performance. To give our users the best experience possible, we will replace these batteries for customers free of charge.
Note: The affected batteries do not pose a safety risk. You may continue to use your current battery until a replacement arrives.
Identifying your battery
The affected batteries have model number A1175 and a 12-digit serial number that ends with U7SA, U7SB or U7SC. To view the model and serial numbers located on the bottom of the battery, you must remove the battery from the computer. The battery serial number is located above the barcode. See photos below. Only batteries within the noted serial number ranges need to be exchanged.
No other MacBook Pro or MacBook batteries are part of this program.
If you have recently purchased an extra battery for your 15-inch MacBook Pro, please check the battery's serial number to see if it needs to be exchanged.
Note: If your battery serial number does not match the requirements listed above, you do not have to exchange your battery.
The Exchange Process
To begin the battery exchange process, you will be asked for the serial number of your 15-inch MacBook Pro, the serial number of your battery and a ship to address.
After serial number verification, a new battery will be shipped to you, free of charge. When you receive the replacement battery, please use the same shipping packaging and included prepaid shipping label to return the recalled battery to Apple.
It is important that you return the affected battery to Apple so that the battery can be properly recycled.
Thank you for your cooperation with this exchange program.
