A couple of years ago (an veritable age in Computer Industry Time) there was a spate of battery recalls as a result of a bad batch made by Sony so imagine our surprise to hear reports of another bunch of batteries going bad. Apparently “Sony 2.15Ah lithium ion cells are a different type of cell from those covered by the much larger recalls and replacement programs that certain PC manufacturers announced in 2006” so that’s okay.
Some 100,000 battery packs worldwide are subject to this voluntarily recall, all of which are 2.15Ah cells. So far Sony says there have been 40 (reported) overheating incidents worldwide, 14 of which were in Europe. Of these “Sony was informed that four incidents involved small burns and 21 included minor property damage.”
As to the cause, Sony reckons “that most of these incidents were related to manufacturing line adjustments made from October 2004 to June 2005, which may have affected some battery cells produced during that period. In addition, there were some incidents that may have involved a raw material flaw.”
This is in addition to Sony recalling Vaio TZs recently because those systems were also overheating. Although the issues shouldn’t be related as “Sony VAIO notebook computers also use different battery cell types, so they are not part of these recalls.” Not that we wish to imply Sony is deliberately sabotaging its competitors’ notebooks.
Sony press release.
