Gateway is taking advantage of Sony's battery replacement program and will exchange approximately 35,000 of its consumers' batteries, it said today.

The exchange program covers batteries that began shipping in September 2005 with laptop PC models CX200, CX210, E100M, M250, M255, M280, M285, M465, M685, MP8708, NX260, NX510, NX560, NX860, NX100, MX1025, MX6918b and MX1020j, the company said in a statement.

The battery cells are thought to contain metallic particles, which under certain circumstances could cause a short circuit resulting in the battery catching fire. About 9.6 million battery packs are thought to contain the cells and about 8 million have already been recalled or offered for voluntary replacement by laptop makers.

Sony plans offer more details of the problems that have hit its battery business today. The recalls and replacements will cost the company around ¥51 billion ($427 million).
