Toshiba to Exchange 340,000 Laptop Batteries
narramissic writes "Toshiba Corp. has offered to exchange 340,000 laptop computer batteries made by Sony. According to a Toshiba spokesman, the batteries may fail to charge correctly, causing the power to cut off suddenly. The company will be posting a software tool to its Web site, allowing customers to identify whether their computer is affected." From the article: "Toshiba's problems stem from a defect in the interface circuitry between the battery cells and the computer. 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 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."
Well, I'll tell you ...
Toshiba's free battery exchange program covers 11 notebook models sold in Japan, five sold in the U.S. and 12 sold in Europe, including the Tecra A7, Satellite A100, Satellite M50 and Satellite pro M70
It's an issue with Lithium-Ion batteries in general. The Sony faults just make the problems even worse for laptops. All Lithium-Ion batteries have safety concerns when exposed to rapid discharging or overcharging. Specifically, the batteries will become quite hot when this occurs beyond a certain rate. My father, who is not normally a tech savy person, has even known about this flaw for years now because of his hobby: Radio Controlled Airplanes.
People who use electric motors on their RC Planes frequently use Lithium Ion batteries, however, because of the nature of the hobby, the batteries tend to discharge at an extremely high rate, or people in a rush can not pay attention and overcharge them. Apparantly there have been many reports over the years in this hobby of planes exploding in mid air or people's cars/homes catching fire because of a rapid buildup in heat by the batteries. The issue got so prevelant that they actually sell pots for people to place their batteries in so that if they do go up in smoke, they won't catch anything else on fire in the process.
Now, of course, this is a hobby where the batteries are being put under unusual and frequent stress, and I'm sure some of the cases were also due to poor quality control. However, it is just one example of many that shows that the problem is not Sony alone, it is a fundamental problem with Lithium-Ion battery technology in the first place. A significant enough problem that the smallest iregularity can result in potentially major issues. All of this is just another example of why, given the increasing portability demands in the technology sector, we need new battery technologies.
You are who you are, let no one tell you different. But, never close your mind to a new point of view.
Nope, the software tool only runs on windows. Which would make sense, as all the machines affected are supplied with windows. You can always just check the PN on the battery: PA3465U-1BAS PA3399U-2BAS PA3400U-1BAS PA3465U-1BRS PA3399U-2BRS PA3400U-1BRS All affected batteries.
