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.

78 MARKING SYMBOLS FOR IDENTIFICATION OF THEIR CHEMISTRY
80 FOREWORD
81 1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
82 all national electrotechnical committees (IEC National Committees). The object of IEC is to promote international
83 co-operation on all questions concerning standardization in the electrical and electronic fields. To this end and
84 in addition to other activities, IEC publishes International Standards, Technical Specifications, Technical Reports,
85 Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC Publication(s)”). Their
86 preparation is entrusted to technical committees; any IEC National Committee interested in the subject dealt with
87 may participate in this preparatory work. International, governmental and non-governmental organizations liaising
88 with the IEC also participate in this preparation. IEC collaborates closely with the International Organization for
89 Standardization (ISO) in accordance with conditions determined by agreement between the two organizations.
90 2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
91 consensus of opinion on the relevant subjects since each technical committee has representation from all
92 interested IEC National Committees.
93 3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
94 Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
95 Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
96 misinterpretation by any end user.
97 4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
98 transparently to the maximum extent possible in their national and regional publications. Any divergence between
99 any IEC Publication and the corresponding national or regional publication shall be clearly indicated in the latter.
100 5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity
101 assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any
102 services carried out by independent certification bodies.
103 6) All users should ensure that they have the latest edition of this publication.
104 7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and
105 members of its technical committees and IEC National Committees for any personal injury, property damage or
106 other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and
107 expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC Publications.
108 8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is
109 indispensable for the correct application of this publication.
110 9) Attention is dra
