HELSINKI, Finland (AP) -- Nokia Corp. warned Tuesday that up to 46 million batteries used in some of its cell phones could be faulty and pose a risk of overheating.
The advisory applies to batteries manufactured by Matsushita from December 2005 to November 2006, the world's largest mobile phone maker said. Matsushita Battery Industrial Co. Ltd. of Japan is one of several suppliers that have together made some 300 million BL-5C batteries.
The lithium-ion battery is one of 14 different types of battery used in Nokia phones.
Nokia said 100 incidents of overheating of the Matsushita-made BL-5C batteries have been reported worldwide, but added that "no serious injuries or property damage have been reported."
"Consumers with a BL-5C battery subject to this advisory should note that all of the approximately 100 incidents have occurred while charging the battery," the Finnish company said. "According to Nokia's knowledge this issue does not affect any other use of the mobile device."
Nokia did not recall the batteries, but said concerned customers could request a replacement for any BL-5C battery affected by the advisory.
Last year, Sony Corp. recalled more than 10 million laptops after it discovered that lithium-ion batteries used in them could overheat and catch fire. The recalls included notebooks made by other major computer makers, including Dell Inc., Lenovo Inc., Apple Inc. and Acer Inc.
Nokia sells products in 130 countries and employs 110,000 people worldwide. In the second quarter, it sold 100 million mobile devices, claiming a 38 percent share of the global market.
