Full title and description
St IEC 62902-2025 — Secondary cells and batteries — Marking symbols for identification of their chemistry. Edition 2.0 (2025). Specifies standardized visual marking symbols, colours and application rules to identify the electrochemical chemistry of secondary cells, batteries, battery modules and monoblocs (battery volume > 900 cm³) for safe handling, installation, operation, decommissioning and recycling.
Abstract
IEC 62902:2025 (Edition 2.0) updates and consolidates requirements for chemistry-identification markings on secondary batteries and related assemblies placed on the market for end use. The document defines symbol design, colours, placement, durability and conditions of use so that battery chemistry (for example lead‑acid, Ni‑Cd, Ni‑MH, Li‑ion, lithium metal) can be clearly identified throughout the product lifecycle, supporting safety and streamlining recycling processes.

Scope
Applies to secondary cells, batteries, battery modules and monoblocs placed on the market for end use when the battery volume exceeds 900 cm³. Defines the marking symbols, layout, colours, minimum durability and application rules necessary to identify the electrochemical chemistry of the unit so that handling, installation, maintenance, decommissioning and recycling operations can be carried out safely and efficiently. This edition replaces IEC 62902:2019 and incorporates clarifications and updated design/durability requirements.
Key topics and requirements
- Standardized chemistry symbols for common technologies (lead‑acid, Ni‑Cd, Ni‑MH, Li‑ion, lithium metal, and any newly specified chemistries).
- Graphic design rules: shape, proportions, colour specifications and minimum size for legibility.
- Mandatory application conditions: recommended placement zones on cells/modules/monoblocs and combination with other safety/handling markings.
- Durability and legibility requirements: resistance to abrasion, solvents, temperature variation and expected service-life exposure.
- Rules for use with recycling and transport markings and instructions for multi‑chemistry battery systems.
- Guidance on marking exceptions, alternative marking techniques and transition provisions from the 2019 edition.
Typical use and users
Manufacturers of secondary cells, battery modules and monoblocs; OEMs integrating battery packs; battery pack assemblers and racking/system integrators; safety and compliance engineers; test and certification bodies; waste management and recycling facilities; transport and handling organizations; regulators and standards committees. Users apply the standard to design durable, unambiguous chemical-identification markings that improve safety and recycling traceability.
Related standards
