Sony recalls PC batteries

SAN FRANCISCO/TOKYO (Reuters) - Sony Corp said five PC makers including Hewlett-Packard Co and Toshiba Corp will recall 100,000 computer battery packs made by the Japanese electronics maker due to a fire hazard.

Sony said the recall is expected to have limited impact on its earnings, and its shares outperformed a falling Tokyo stock market on Friday.

The recall is a fraction of a much bigger recall of 9.6 million Sony PC batteries in 2006, which cost the company around 35.5 billion yen ($360 million).

The U.S. government issued on Thursday a recall of 35,000 Sony batteries and the Tokyo-based company said it would recall a further 65,000 batteries worldwide.

PC makers have reported 40 cases of overheating, including four cases where users suffered minor burns, and 21 cases of minor damage from fires and overheating, a Sony spokeswoman said.

The recall affects around 74,000 notebook PCs sold by HP and 14,400 from Toshiba.

The faulty batteries are also used in laptop PCs from Dell Inc, Acer Inc and Lenovo Group Ltd, Sony said.

Sony blamed the faulty batteries on factory changes dating back up to four years, which it believes may have affected the quality of some battery cells.

Other incidents of overheating may have involved a problem with raw materials, the company said.

Sony recalled last month 438,000 of its Vaio laptops due to concerns about overheating batteries.

Shares in Sony rose 3.5 percent to 2,350 yen, compared with a 0.7 percent slide in the Nikkei average.
