Sony isn't the only company having
battery problems the days. It was announced today that Mitsubishi Electric Corp.
and NTT DoCoMo Inc. are recalling 1.3
million batteries used in cell phone handsets.
The batteries were manufactured by the Sanyo GD Soft Energy
Co. subsidiary of Sanyo Electric Co. DoCoMo has received confirmation of one
incident in which a battery ruptured after overheating, while another seventeen
cases are being investigated.
The actual cause for the overheating batteries has been
linked to defective electrode plates that can pierce a battery cell's internal
insulation. From that a point, a short circuit can occur causing the cell to
overheat and rupture.
As a result of the recall, Mitsubishi FOMA D902i, D902iS and
D903i handsets have been taken out of production and customers are being
contacted with instructions on how to identify and get replacements for
