Hewlett-Packard has issued a worldwide recall for another 54,000 lithium-ion batteries used in HP and Compaq computers after receiving reports of injuries from the batteries overheating and rupturing.
The recall was announced by the US Consumer Product Safety Commission and expands an earlier recall of 70,000 of the same type of batteries.
The recall said the batteries could overheat and burn users, and they posed a fire risk.
The earlier recall came after two reports of the batteries overheating.
The commission said that since then, HP has received 38 additional reports of the batteries overheating, causing 11 minor injuries.
Those people were burned when they handled computers whose batteries had ruptured, said CPSC spokesman Scott Wolfson.
Batteries can rupture if they've been charged too long and don't have a good way to regulate the excess heat.
Wolfson said that the industry was working to change that.
HP says the computers at issue were sold in stores and online from August 2007 through July 2008.
The battery packs were also sold separately.
Laptop users can check whether a battery is affected by the recall on HP's website.
Affected batteries will be replaced for free.
The recall pales in comparison to the recall in 2006 and 2007 of nearly 10 million of a model of Sony batteries that were used by almost every major PC manufacturer.
