Apple is offering to exchange batteries in its 15-inch MacBook Pro notebooks sold between February to May of this year.

Apple’s statement reads in part: “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.”

Apple hasn’t offered an explanation as to what is wrong with the batteries, although the website does clearly state that they don’t pose a security risk.

The affected batteries have model number A1175 and a 12-digit serial number ending in U7SA, U7SB or U7SC.

As part of the exchange program, a new battery will be shipped to users who have verified the serial number on their batteries; then they will have to send back the recalled battery.
