Apple is recalling 1.8 million lithium-ion batteries for its iBook and PowerBooks, just a week after Dell's largest-ever battery recall.

The batteries are also made by Sony Energy Devices and could overheat, posing a fire hazard to consumers, the US Consumer Product Safety Commission warned on Thursday.

Apple has counted nine reports of overheating, including two instances that caused minor burns from handling the hot computers, the commission said. The batteries were used with the following computers: 12-inch iBook G4, 12-inch PowerBook G4, and 15-inch PowerBook G4. No other Apple PC models are involved.

Affected consumers are advised to contact Apple or go to a dedicated page on Apple's website to check the battery's serial number and request a replacement.
