Apple has initiated a worldwide battery exchange program for certain rechargeable batteries that were sold for use with 15-inch MacBook Pro computer systems from February 2006 through May 2006. The company says they “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.” In addition Apple says the “affected batteries do not pose a safety risk. You may continue to use your current battery until a replacement arrives.”
