This document specifies methods for the clear identification of secondary cells, batteries, battery modules and monoblocs according to their chemistry (electrochemical storage technology). The markings described in this document are applicable for secondary cells, batteries, battery modules, and monoblocs where they are placed on the market for end use and their battery volume exceeds 900 cm3. The marking of the chemistry is useful for the installation, operation and decommissioning phases of battery life. Many recycling processes are chemistry specific, thus undesired events can occur when a battery which is not of the appropriate chemistry enters a given recycling process. In order to ensure safe handling during sorting and recycling processes, therefore, the battery is marked so as to identify its chemistry. This document defines the conditions of utilization of the markings indicating the chemistry of these secondary batteries. The details of markings and their application are defined in this document. NOTE 1 Nothing in this document precludes the marking of batteries with recycling and chemistry symbols required by state, federal, national or regional laws or regulations or with a seal under license by a national recycling program. NOTE 2 The 900 cm3 limit has been chosen because it is a reasonable compromise between larger format batteries and small batteries. On small batteries, the space for additional labels is limited which may result in a readability conflict.
