Apple has determined that certain lithium-ion batteries containing cells manufactured by Sony Corporation of Japan pose a safety risk that may result in overheating under rare circumstances.

The affected batteries were sold worldwide from October 2003 through August 2006 for use with the following notebook computers: 12-inch iBook G4, 12-inch PowerBook G4 and 15-inch PowerBook G4.

Apple is voluntarily recalling the affected batteries and has initiated a worldwide exchange program to provide eligible customers 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.

Identifying your battery

Please use the chart below to identify the battery model and serial numbers that apply to your iBook or PowerBook. If the first 5 digits of your battery’s 12-digit serial number fall within the noted ranges, please order a replacement battery immediately.

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 barcode. See photos below.

Computer model	Battery model number	Battery serial number range
12-inch iBook G4	A1061	ZZ338 – ZZ427 3K429 – 3K611 6C519 – 6C552 ending with S9WA, S9WC or S9WD
12-inch PowerBook G4	A1079	ZZ411 – ZZ427 3K428 – 3K611
15-inch PowerBook G4	A1078 and A1148	3K425 – 3K601 6N530 – 6N551 ending with THTA, THTB, or THTC 6N601 ending with THTC

Note: After removing the recalled battery from the iBook or PowerBook, consumers should plug in the AC adapter to power the computer until a replacement battery arrives.

If you participated in a previous battery recall for any of these computer models or recently purchased or received from Apple an extra battery for an iBook G3, please check your battery serial number in case you received a replacement battery that is affected by this program.

National and regional resellers, catalogers, and Apple’s on-line and retail stores sold the computers with the batteries from October 2003 through August 2006. These batteries were also sold separately and may have been supplied as service replacement units.

The Exchange Process

To begin the battery exchange process, you will be asked for the serial number of your iBook G4 or PowerBook G4, the serial number of your battery and a shipping address.

Customers in Australia and Asia (excluding Japan) should contact their local Apple Authorized Service Provider to obtain a replacement battery.

After serial number verification, a new battery will be shipped to you, free of charge. When you receive the replacement battery, please use the same shipping packaging and included prepaid shipping label to return the recalled battery to Apple for proper disposal.

Note: If your battery serial number does not match any of the ranges listed above, you do not have to exchange your battery.

Thank you for your cooperation with this exchange program.
