Thanks All,
I guess that stumping up the £86 quoted is nearly as good as buying it direct on the ebay auction listed above. (So much for cheap auctions!)
I have a Fujitsu recycler near to me so will ring them and ask if they have any batteries for the models that Richard has kindly listed, otherwise will go back to my source.
The recyclers seem to deal in small batteries only, and the only one that quotes lappy batts is more expensive than a new battery! (So much for recycling)
Seems they have us all by the lappies.......ouch!!
