The U.S. Consumer Product Safety Commission has announced a recall of 70,000 lithium-ion batteries used in Hewlett-Packard and Compaq laptops. Apparently, there have been at two reported cases where the batteries caught on fire.
The battery packs were sold separately and in laptops between August 2007 through March 2008. Naturally, if you think you might be affected, it might be a good idea to check and see if your battery matches the ones pictured in the gallery before using it again.
