Fujitsu will offer owners of some of its laptop computers replacement batteries as part of Sony's global battery exchange programme, it said on Saturday.

Sony announced the scheme late last week 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 its machines, but following recalls from other PC vendors the companies are offering replacements to ease customers' concerns.

The Fujitsu models are: FMV Biblo Loox P-series P70R and P70S; and the Biblo Loox T-series T50M, T50R, T50RN, T50S, T50SN, T70M, T70M/T, T70MN, T70R, T70R/T, T70RN, T70S, T70S/V and T70SN.

On Friday Toshiba said it would offer replacement batteries for around 830,000 PCs under the Sony programme.
