Uniross 9V PP3 170mAh Rechargeable batteries reduced to 47pence in Currys. Found these in the East Kilbride store , they had 20 -30 left on the shelf. Not sure if it is available in any other store. Looks like they are old stock and they are making way for the ones in new packaging. Good deal as the other makes on the shelves were £6.99.
