KDDI to replace about 2 million Sony-Made Batteries in Phones marketed since 2007

KDDI Japan’s second-largest mobile-phone operator will recall about 2 million of its cellphones marketed since 2007 for free repairs after two reported cases of battery packs heating up. The batteries in question were manufactured by a subsidiary of Sony. The batteries may produce heat and melt, KDDI said today after investigations following two customer complaints in 2010 and six this year. The recall affects three models made by Casio and Hitachi and sold between 2007 and 2009.

The cost of the replacements and who will bear it hasn’t been determined
