Sony Corporation will initiate a global replacement program for certain battery packs that utilize Sony-manufactured lithium ion cells used by notebook computer manufacturers, in order to address concern related to recent over-heating incidents. This development comes after a number of OEMs—Dell, Lenovo, IBM, Apple, Toshiba—have initiated recalls of their own.

Sony is discussing this plan with the US Consumer Product Safety Commission and will coordinate with other government authorities as required.

In rare instances the battery packs have started fires when microscopic metal particles in the battery cells come into contact with other parts of the battery cell, leading to a short circuit within the cell. Typically, a battery pack will simply power off when a cell short circuit occurs. However, under certain rare conditions an internal short circuit may lead to cell overheating and potentially flames. The potential for this to occur can be affected by variations in the system configurations found in different notebook computers.

Sony announced it will consult with its OEM customers that utilize these battery cells, to work with those that choose to participate in regards to the replacement of battery packs.
