HP has now recalled over 120,000 batteries during the last 12 months, adding 54,000 to its recall list, citing concerns over the cells splitting, overheating, and fire.
HP has the details:
On May 19, 2010, HP expanded a worldwide voluntary recall and replacement program in cooperation with various government agencies, adding battery packs to the replacement program announced on May 14, 2009 and revised on October 15, 2009. Product model series were also added to the list of products that may have been sold with affected batteries. HP customers affected by this program will be eligible to receive a replacement battery pack for each verified, recalled battery pack at no cost.
We are taking this action as part of our commitment to provide the highest quality of service to our notebook customers. We are proactively notifying you of this issue and are prepared to replace all verified battery packs.
HP and the battery manufacturers believe that certain battery packs shipped in HP notebook PC products manufactured between August 2007and May 2008 may pose a potential safety hazard to customers. The batteries can overheat, posing a fire and burn hazard.
According to HP, less than 3% of the notebook PC products manufactured from August 2007 to May 2008 and included in the program, contained battery packs that are affected.
