Hewlett-Packard Co is expanding a voluntary recall of notebook computer batteries due to risk of fire from overheating, the company and the U.S. Consumer Product Safety Commission said on Friday.

The commission said that since an initial recall in May 2010 and 2009, HP has received additional reports of overheated and ruptured lithium-ion batteries, leading it to expand its recall to include more models.

The recall relates to 162,600 additional batteries, manufactured in China and imported by Hewlett-Packard.
