Lenovo Group and IBM are recalling 1,68,500 battery packs sold in the United States and about 3,57,500 packs sold internationally along with IBM's ThinkPads, the U.S. Consumer Product Safety Commission said.According to a report on the website of Reuters, Sony, separately, initiated a global replacement program for lithium-ion batteries it made for notebook PC companies saying short circuits could occur on rare occasions when tiny metal particles come in contact with other parts of the batteries.Lenovo and IBM's move to recall ThinkPad batteries brings the number of battery cells recalled to more than six million since Dell in August said it was recalling 4.1 million notebook batteries made by Sony. Apple Computer on August 25 announced a recall of 1.8 million lithium-ion batteries made by Sony, the report said.
