Fujitsu is to offer owners of some of its laptop computers replacement batteries as part of Sony's global battery exchange programe.

Sony announced the programme in response to growing consumer concerns about its laptop PC batteries, which are used by many companies. Since mid-August, about 6.6 million laptop batteries containing Sony-made cells have been recalled by computer makers because of a potential fire hazard.

Fujitsu said it believes there is no danger in using Sony-made batteries in their machines, but following recalls from other PC vendors the companies are offering replacements to ease customers' concerns.

Those sold outside Japan covered by the exchange are: Lifebook P1510, P1510D, P7120, P7120D, S7020, S7020D, S7025, S7025D, C1320 and C1320D.
