NEW YORK (CNNMoney.com) -- Apple is recalling 1.8 million battery packs for its iBook and PowerBook notebook computers due to an overheating problem, the Consumer Product Safety Commission (CPSC) announced Thursday.
The cells in the lithium-ion batteries in the iBook G4 and PowerBook G4 computers - the only two models affected by the recall - were produced by Sony.
Apple consumers with affected products should stop using the recalled batteries immediately and contact Apple for a replacement battery, free of charge.
Consumers should remove the batteries from their notebooks and use the AC adapter to power their computers.
