Toshiba is recalling a small batch of laptop batteries that could overheat and burn users, a company spokesman said Thursday.

About 5,100 Sony-made lithium-ion batteries are defective, spanning 10 models of Toshiba computers, some of which are essentially the same model but carry a different name in different regions, said Manuel Linnig, Toshiba spokesman in Germany.

The latest recall involves a different type of battery than in September 2006 when more than 8 million rechargeable lithium-ion batteries made by Sony were recalled.
