Found this on Neowin:
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.
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.
The affected batteries have model number A1175 and a 12-digit serial number that ends with U7SA, U7SB or U7SC.
Mine was one of those affected. I was thinking the battery life was a little weak – glad they realized it too!
