What is to do with used batteries within telecommunications services?

The authors consider what is to be done with used batteries that contain hazardous substances. It is emphasized that an international standard on types of cells and batteries that have to be returned to the manufacturer is necessary for batteries that are used by the common public. The International Recycling Symbol ISO 7000-1135 has been proposed for the marking; a coming EEC directive will specify the marking of certain batteries with this symbol. In parallel, IEC-TC 21, Secondary Batteries, and IEC-TC 35, Primary Batteries, are preparing standards for a method of marking of certain batteries with the ISO symbol. In some European countries the battery industry has already started to mark such batteries as starter batteries, sealed nickel-cadmium batteries, small portable valve-regulated lead-acid batteries, and mercury button cells. In addition, regulations will be prepared to mark devices and equipment containing built-in batteries
