Apple has announced a recall for 1.8 million lithium-ion notebook batteries due to the same overheating issues that moved Dell to recall 4.1 million units last week. In both cases the devices were manufactured by Sony. The affected batteries were sold worldwide between October 2003 and August 2006 for use in the 12-inch iBook G4, 12-inch PowerBook G4 and 15-inch PowerBook G4. Consumers are advised to remove the batteries and use the AC adapter until a replacement arrives.
