§ Mr. Pavitt
asked the Secretary of State for Social Services if he will estimate the saving which will accrue to the National Health Service by replacing 675 hearing-aid batteries by double life CP101 batteries.
§ Mr. Newton
Zinc-air batteries of type CP101 are not suitable for all types of hearing aid but it is estimated that they can meet almost two-thirds of the Department's requirements. On this basis the annual savings from their use will be about £240,000 at current prices.
