Apple has recalled 28,000 of the batteries used in its 15in aluminium PowerBook G4 laptop computers sold earlier this year in the US and via its online and retail stores, after receiving four reports of the batteries overheating.
Apple has reported the fault to the US Consumer Product Safety Commission (CPSC).
The CPSC said yesterday that an internal short triggers the fault, causing the lithium ion rechargeable batteries to overheat.
Apple said in a statement: "The affected batteries could overheat, posing a fire hazard. Apple received four reports of these batteries overheating. No injuries have been reported.
"Apple urges you to stop using your battery and to order a replacement battery immediately. If you continue to use your battery, do not leave it unattended and check for signs of overheating."
Both the CPSC and Apple advised customers affected by the fault to contact Apple immediately.
The vendor said it has made provision to supply replacement batteries free of charge by arrangement with the battery's South Korean manufacturer, LG Chem Ltd.
Those laptops affected were sold in national and regional US resellers, catalogues and through Apple's online and retail stores between January and August 2004, at a cost of $2,000 to $2,600 (£1,096 to £1,425). The batteries also retailed separately for about $130.
The batteries were all manufactured in Taiwan in December 2003, before being shipped with model number A1045 G4 laptops. The serial numbers of affected batteries begin with HQ404, HQ405, HQ406, HQ407 or HQ408.
No other Apple products have been affected by this recall. More information on Apple's exchange process can be found here.
