To find out if you qualify, go to www.apple.com/support/13inch-macbookpro-battery-replacement and enter your serial number.
To have your battery replaced, you must send your MacBook Pro to Apple, take it to an authorized service provider, or book an appointment at an Apple Store.
The program has been running for 5 years from the sale date, so you have plenty of time to profit from it.
