The following information is provided from an Apple Safety Recall message:
“Apple is voluntarily recalling certain lithium-ion rechargeable batteries that were sold worldwide, in systems and separately, from October 2004 through May 2005 for use with the following computers: 12-inch iBook G4, 12-inch PowerBook G4, 15-inch PowerBook G4. These batteries were manufactured by LG Chem, Ltd. of South Korea. Apple has initiated a worldwide exchange program and will provide you with a new replacement battery, free of charge. This program is being conducted in cooperation with the U.S. Consumer Product Safety Commission (CPSC) and other international safety authorities.
Issue: The affected batteries could overheat, posing a fire hazard. Apple received six consumer reports of these batteries overheating. Apple urges you to stop using your battery and to order a replacement battery immediately. If you must temporarily use your computer with the battery, do not leave it unattended and check for signs of overheating.
Product: The recalled batteries include those with model numbers A1061, A1078, and A1079 and serial numbers that begin with HQ441 through HQ507 and 3X446 through 3X510. To view the model and serial numbers labeled on the bottom of the battery, you must remove the battery from the computer. The battery serial number is printed in black or dark-grey lettering beneath a bar code.
What to do: To begin the battery exchange process, go to the Apple website at {http://www.apple.com/support/batteryexchange}. You will be asked for the serial number of your computer, 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. You may exchange up to three batteries through the Web site. When you receive the replacement battery, please use the same shipping packaging and the included prepaid shipping label to return the recalled battery to Apple. If you do not have access to the Web site listed above, you can call Apple at 1-800-275-2273 between 8 a.m. and 8 p.m., central standard time, seven days a week, for further assistance.
Thank you for your cooperation with this exchange program.”
