U.S. Consumer Product Safety Commission will investigate all Sony lithium-ion batteries meant for laptops.

After Dell announced that they will recall 4.1 million notebook batteries because it is possible for these batteries to overheat, which could cause a fire.

Sony batteries are used in most of the notebooks coming from HP, Dell, Apple and Lenovo. This is why they will be investigated so the risks of laptops bursting in flames to reduce.

“We are looking at the complete scope of the batteries made by Sony to ensure that no other consumers are in harm’s way,” U.S. Consumer Product Safety Commission spokesman Scott Wolfson said. “We recognize that the batteries manufactured by Sony are not unique to just the Dell notebook computers.”

Until now, no injuries have been tied to these products but Dell said it has received six reports of batteries overheating since December, causing damage to furniture and other items.

“It’s probably not Dell-specific,” said the president of market researcher Endpoint Technologies Associates, Roger Kay. “If they have the Sony cell, specifically the cell made between April 2004 and June 2006, they have the problem.”

He estimated the recall could cost $200 million to $300 million, depending on how many customers participate.

Dell said it expected no “material” financial impact from the recall, while Sony said its cost from the recall has not yet been determined.
