BS EN IEC 62902:2019

This standard BS EN IEC 62902:2019 Secondary cells and batteries. Marking symbols for identification of their chemistry is classified in these ICS categories:

• 29.220.30 Alkaline secondary cells and batteries
• 29.220.20 Acid secondary cells and batteries

IEC 62902:2019 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 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 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.
IEC 62902:2019 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.
