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 standard are applicable for secondary cells, batteries, battery modules and monoblocs with a volume of more than 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 may occur when a battery which is not of the appropriate chemistry enters a given recycling process. Therefore, in order to ensure a safe handling during sorting and recycling processes, it is necessary to mark the battery so as to identify its chemistry. This standard 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 standard. NOTE: Nothing in this standard should preclude 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.
