Nokia's recent announcement  to replace BL-5C batteries may end up costing the battery manufacturer, Matsushita, JPY 10 billion (US$ 86 million.) It was only this month when Nokia announced that the batteries may overheat while charging. Two cases have already been filed in Japan of overheating, one classified as a fire. The call to replace will be affecting 46 million batteries manufactured by Matsushita.

Although a subsidiary of Matsushita - Matsushita Battery Industrial Co - will cover the costs of the repairs, the main company would still be affected. Some Japanese analysts speculate that because of the incident, the financial cost would extend to the company's stocks which may end up losing up to JPY 138 billion (US$ 1.18 billion.) The company already slid down 5% since the announcement half a month ago.

Nokia Japan President Tyler Mcgee apologized with a deep bow in front of a news conference. He also says that customer safety and product quality are Nokia's top priorities and explains that he was not aware of cases of batteries overheating outside of Japan until Nokia made the announcement on August 14.
