Secondary cells and batteries - Marking symbols for identification of their chemistry
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.
Sekundärbatterien - Symbole für die Kennzeichnung zur Identifikation ihrer Chemie
Batteries et éléments d'accumulateurs - Symboles de marquage pour l'identification de leur caractéristique chimique
L'IEC 62902:2025 spécifie les méthodes permettant d’identifier clairement les batteries d’accumulateurs, batteries, modules de batteries et monoblocs selon leur caractéristique chimique (technologie de stockage électrochimique).
Les marquages décrits dans le présent document s’appliquent aux:
- accumulateurs;
- batteries;
- modules de batteries;
- monoblocs,
lorsqu’ils sont mis sur le marché en vue d’une utilisation finale et lorsqu'ils ont un volume de batterie supérieur à 900 cm3.
Le présent document définit les conditions d’utilisation des marquages indiquant la caractéristique chimique de ces batteries d’accumulateurs.
