100,000 laptop battery packs made by Sony Corporation will be recalled after 40 reports of overheating were investigated by the US Consumer Product Safety Commission.

The recall involves Sony 2.15Ah lithium-ion cell batteries that were made in 2004 and 2005 and sold globally in HP, Dell and Toshiba laptops. Certain Acer and Lenovo models are also believed to be affected.

Some reports complained of overheating coupled with flames and fire. A few even complained of minor burns and property damage.

35,000 batteries will be recalled in the United States and a further 65,000 in other parts of the world.

If you think you’re affected, remove your laptop battery and contact the manufacturer or dealer for more information, and request a replacement if necessary.

Sony said the defect was due to adjustments made on its manufacturing line from October 2004 to June 2005, and a possible flaw in the metal foil for electrodes.

Sony confirmed that the defective batteries were not used in its Vaio line, though the company recently had to recall nearly 440,000 Vaio notebooks globally because of a wiring fault that could also potentially cause overheating.
