Toshiba is not recalling but rather “offering to exchange” a total of 340,000 notebook batteries. Toshiba emphasizes there is no overheating or fire risk with these batteries, such as with the Dell and Apple recall, but rather the faulty batteries may cause the computer to randomly shut down causing loss of unsaved work.
The list of affected batteries can be found on the Toshiba website. Popular laptops such as the Toshiba Satellite A100, Satellite M100, Tecra A7 and Satellite M50 may be affected. Tuesday’s recall affects 100,000 laptop batteries in the U.S., 45,000 in Japan, and the rest in other parts of the world.
The faulty batteries, made by Sony, might fail to charge correctly, causing the power to cut off suddenly if the notebook is not connected to a mains outlet, said Toshiba spokesman Keisuke Ohmori. Toshiba’s batteries are not at risk of starting a fire, Ohmori said. “There is no such hazardous or related issue.”
The battery problem stems from a defect in the interface circuitry between the battery cells and notebook. That defect is caused by corrosion, said a spokesman for Sony, the manufacturer of the batteries. An ingredient used in the insulating paper of batteries manufactured between March and May of 2006 can corrode components in the batteries’ charging circuits, causing them to fail, said Sony spokesman Takashia Uehara. The supplier changed the composition of the insulating paper without notice, he said.
Batteries made for other notebook manufacturers also contained the paper, and Sony is working with those companies to see whether there is a problem, Uehara said. He declined to say how many batteries were affected overall.
