Hewlett-Packard is adding to the list of notebook battery models that pose a safety hazard, according to the Consumer Product Safety Commission.
HP has voluntarily recalled an additional 162,600 lithium ion batteries used in some HP and Compaq notebooks sold between July 2007 and July 2008. The batches of batteries included with 31 models of its notebooks can "overheat and rupture, posing fire and burn hazards," according to the CPSC.
The latest round of batteries being recalled is in addition to the 70,000 recalled in May 2009 and 54,000 in May 2010, all for the same reason: potential to overheat and rupture. Since last year's recall, 40 incidents of faulty batteries overheating or rupturing have been reported. The result has been seven burn injuries, one injury due to smoke inhalation, and 36 counts of property damage.
The CPSC is urging customers who were informed during prior recalls that their notebook and battery was not at risk to check again to see if their product is on the list. If it is, the CPSC says to remove the battery immediately and order a new one from HP, which will replace it for free.
