Welcome to a laptop battery specialist of the Toshiba Laptop Battery
Sony has finally bitten the bullet and issued a worldwide recall of all Sony-manufactured lithium-ion batteries used in notebook computers. Earlier in the day, Lenovo/IBM joined the ranks of Dell, Apple, and Toshiba in issuing a recall for all Sony batteries that ship with their notebooks.
The Tokyo-based electronics manufacturer says that the recall is to address concerns regarding "recent overheating incidents," and that they are working with the Consumer Product Safety Commission to formulate a plan for the recall. They cite microscopic metal particles that enter the battery such as Toshiba PA3635U-1BRM Battery , Toshiba PA3636U-1BRL Battery , Toshiba PA3728U-1BRS Battery , Toshiba PA3817U-1BRS Battery , Toshiba PABAS228 Battery , Toshiba PA3818U-1BRS Battery , Toshiba PA3634U-1BAS Battery , Toshiba Portege M800 Battery , Toshiba Satellite L310 Battery , Toshiba Satellite L510 Battery , Toshiba Portege T130 Battery , Toshiba Satellite U400 Battery during the manufacturing process as the reason for the battery failures. The particles, they say, come into contact with other parts of the battery cell, causing the battery to short-circuit. Sony claims that these batteries would normally just power off, but in "rare cases" may overheat and cause flames.
Indeed, flames have been the result of many Sony battery malfunctions in the news lately, most recently from a Lenovo ThinkPad bursting into flames at a Los Angeles airport just last week. Such dramatic incidents happening in airports or—even worse—in-flight have passengers and airlines getting antsy, with three airlines now putting wide restrictions on laptop use due to the recalls. Virgin Atlantic recently eased their restrictions on Dell and Apple laptops to just those whose batteries fit the list.
Between Dell, Apple, Toshiba, and Lenovo, the number of recalled batteries worldwide is climbing past 7 million. Sony, being one of the largest lithium-ion battery manufacturers in the world, undoubtedly supplies other vendors (not to mention themselves) aside from those under the recall, so that number is sure to climb. Sony says that they plan to consult with OEM customers who wish to participate in the recall, so if your battery is a Sony that hasn't already been exchanged, keep an eye out for information through your notebook manufacturer. When are those battery standards coming again?
