Hewlett-Packard Co. is voluntarily recalling lithium-ion batteries used in HP Pavilion, Compaq Presario, HP, and HP Compaq because of fire hazard, the U.S. Consumer Product Safety Commission announced Thursday.

Hewlett-Packard has recalled 70,000 laptop batteries that pose a fire and burn hazard to users.

The company warned that “the recalled lithium-ion batteries can overheat, posing a fire and burn hazard to consumers.

HP said it is aware of two reports of batteries that have overheated and ruptured, resulting in flames that caused “minor property damage.” However, no injuries have been reported.

The systems that have these batteries were sold through computer and electronics stores nationwide and HP's Web site from August 2007 through March 2008. The laptops cost between $500 and $3,000. The batteries also were available separately for between $100 and $160.

The battery manufacturer was not named, but the product was built in China.

Consumers are advised to remove the recalled battery from their notebook computer and contact HP to see if their battery is included in the recall and to request a free replacement battery.

HP is offering replacement batteries at no charge and has a Web site that provides additional details. Customers also can call 800-889-2031 to get support.
