BS EN IEC 62902:2025 - TC

This standard BS EN IEC 62902:2025 - TC Tracked Changes. 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 62902:2025 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 to - secondary cells, - batteries, - battery modules, and - monoblocs, when they are placed on the market for end use and when their battery volume exceeds 900 cm3. The chemistry marking is useful for the installation, operation and decommissioning phases in the battery's life cycle. This document defines the conditions of use of the markings indicating the chemistry of these secondary batteries.
