This document provides requirements and recommendations on environmental aspects of secondary lithium, nickel cadmium and nickel-metal hydride cells and batteries for portable applications (hereafter referred to as relevant secondary cells and batteries ). Relevant secondary cells and batteries are specified in the scopes of IEC 61960-3, IEC 205 61960-4, IEC 61951-1, IEC 61951-2. NOTE Portable applications are defined in IEC 61960-3 as the following: Portable applications comprise hand-held equipment, transportable equipment, and movable equipment. See IEC 61960-3 for examples. This document is not intended to be applied for batteries embedded in end-use products. Once the embedded battery is removed from an end-use product, this document becomes applicable to it. The safety and control circuits as well as cases associated with relevant secondary batteries, but not part of an end-use product, are covered by this document as parts of the relevant secondary batteries. NOTE See Annex A and C for examples of regional regulations applicable and not applicable to batteries.
