(InfoWorld) - Fujitsu'sÂ recall of defective batteriesÂ will affect 287,000 notebook PCs, including 63,000 in Japan, the company said Wednesday. Fujitsu last week became the fifth recent PC vendor to recall batteries using lithium-ion cells made by Sony Energy Devices. A manufacturing defect can cause those cells to short circuit, overheating and in some cases catching fire. So Fujitsu has asked both users of certain notebook PCs and dealers with unsold computers in their inventory to return the affected batteries, said Sean Nemoto, investor relations manager for Fujitsu. Dell started the rush when it announced on Aug. 14 it wouldÂ recall 4.1 million batteries, following complaints from a handful of customers that their PCs had burst into flames. Other vendors quickly followed, includingÂ Apple Computer,Â Toshiba,Â Lenovo Group, IBM, andÂ Fujitsu. Together they have recalled 7.9 million batteries. Sony has beenÂ pushing vendors to recall its batteriesÂ even in the absence of customer complaints. Sony said Thursday that it was working with the U.S. Consumer Product Safety Commission to recall any remaining defective cells in notebooks worldwide. The move will not affect other types of consumer electronics that use lithium-ion cells, such as cameras and music players. Notebook vendors insist that the number of actual fires is very small, amounting to just fractions of a percent compared to the many millions of batteries recalled. The Consumer Product Safety Commission has counted 47 incidents of smoke or fire coming from notebook computers from January 2001 to August 2006. Sony and the vendors continue to debate whether the fault lies solely in battery cell manufacturing, or also in the design of notebook PCs. Sony designs its batteries to shut down after a short circuit, but in certain occasions they will continue to overheat. "The potential for this to occur can be affected by variations in the system configurations found in different notebook computers," the company said. Hewlett-Packard said Monday that its customers had not experienced any overheated batteries thanks to redundant safety features used in HP notebooks. "Because of HP's PC system configuration, HP notebooks using Sony battery cells are not prone to overheating issues that have recently been observed," the companies said in a joint statement. However, other vendors insist their designs are also safe. Dell's recall is careful to state that "only the described batteries are subject to this recall and not the notebook computers themselves."

(InfoWorld) - NTT DoCoMo and Mitsubishi Electric are planning to replace around 1.3 million batteries manufactured by Sanyo Electric because they may overheat and catch fire, the companies said Thursday. The batteries were manufactured before June of this year and are used in NTT DoCoMo's D902i handset. Some may have also been used in two other models of Mitsubishi Electric phone, the D902iS and D903iS, the companies said. The batteries carry the model number "D06." "In rare cases there is a slight deformation of the electrode plate which causes it to come into contact with the insulation sheet and hence the insulation sheet can become damaged," said Richard Sedgwick, a spokesman for Sanyo in Tokyo. "If the battery was also damaged through an outside side, for example if the user dropped the battery, then the problem could occur." NTT DoCoMo said it has confirmed one case of the battery rupturing because of the problem and knows of 17 other cases where the D06 battery has ruptured or overheated. The carrier said the battery had been subject to an "extremely strong impact" in a number of the cases. Sanyo said it began examining ways of strengthening the electrode in April this year as a precautionary measure against possible problems, but at the time had not heard any reports about actual problems. Batteries with stronger plating on the electrode began rolling off the company's production line in June, hence Thursday's advisory only concerns batteries manufactured until May. The problem brings back memories ofÂ Sony's battery problemsÂ of earlier this year. Around 9.6 million Sony-manufactured laptop computer batteries were recalled or voluntarily replaced by many laptop PC vendors after batteries in several PCs overheated and caught fire. The problem was traced back to metal particles that had gotten into the battery during manufacturing. Sony estimated the problems will cost it around Â¥51 billion ($444 million) this financial year. Sanyo said that it has yet to work out with NTT DoCoMo and Mitsubishi Electric the part it will play in the replacement. Sanyo and Sony are two of the world's largest manufacturers of Lithium Ion batteries.
