IEC 61960-4:2024 specifies performance tests, designations, markings, dimensions and other requirements for coin secondary lithium cells and batteries for portable applications, watches, and backup power supply such as memory backup applications. In particular, watch‑specific requirements are specified in Annex A. This document provides purchasers and users of coin secondary lithium cells and batteries with a set of criteria with which they can assess the performance of coin secondary lithium cells and batteries offered by various manufacturers. This document defines a minimum required level of performance and a standardized methodology by which testing is performed and the results of this testing are reported to the user. This document covers coin secondary lithium cells and batteries with a range of chemistries. Each electrochemical couple has a characteristic voltage range over which, during discharge, it releases its electrical capacity, a characteristic nominal voltage and a characteristic end‑of‑discharge voltage. Users of coin secondary lithium cells and batteries are requested to consult the manufacturer for advice. This document also provides guidelines for designers of equipment using lithium batteries (voir l'Annexe B).

L'IEC 61960-4:2024 spécifie les essais de performance, les désignations, les marquages, les dimensions et autres exigences pour les éléments et batteries d'accumulateurs boutons au lithium destinés aux montres, aux applications portables et d'alimentation de secours telles que les applications de sauvegarde de mémoire. Les exigences propres aux montres, en particulier, sont spécifiées dans l'Annexe A. Le présent document fournit aux acheteurs et aux utilisateurs d'éléments et batteries d'accumulateurs boutons au lithium un ensemble de critères au moyen desquels ils peuvent évaluer les performances des différents accumulateurs de ce type proposés par différents fabricants. Le présent document définit un niveau d'exigence minimale de performance et une méthodologie normalisée par laquelle sont réalisés les essais dont les résultats sont mis à la disposition de l'utilisateur. Les utilisateurs sont alors en mesure d'apprécier par eux-mêmes la viabilité des accumulateurs disponibles dans le commerce au moyen de la spécification déclarée et donc de sélectionner l'élément ou la batterie le ou la mieux adaptée à l'application prévue. Le présent document couvre les éléments et batteries d'accumulateurs boutons au lithium dans une large gamme de compositions chimiques. Chaque couple électrochimique possède une plage de tension caractéristique dans laquelle il restitue, en décharge, sa capacité emmagasinée, une tension nominale caractéristique et une tension de fin de décharge caractéristique. Il est demandé aux utilisateurs d'éléments et batteries d'accumulateurs boutons au lithium de prendre conseil auprès du fabricant. Le présent document fournit également des lignes directrices pour les concepteurs d'équipements utilisant des batteries au lithium (voir l'Annexe B).

65 FOREWORD
66 1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
67 all national electrotechnical committees (IEC National Committees). The object of IEC is to promote internation al
68 co-operation on all questions concerning standardization in the electrical and electronic fields. To this end and
69 in addition to other activities, IEC publishes International Standards, Technical Specifications, Technical Reports,
70 Publicly Available Specifications (PAS) and Guides (hereafter referred to as "IEC Publication(s)"). Their
71 preparation is entrusted to technical committees; any IEC National Committee interested in the subject dealt with
72 may participate in this preparatory work. International, governmental and non-governmental organizations liaising
73 with the IEC also participate in this preparation. IEC collaborates closely with the International Organization for
74 Standardization (ISO) in accordance with conditions determined by agreement between the two organizations.
75 2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
76 consensus of opinion on the relevant subjects since each technical committee has representation from all
77 interested IEC National Committees.
78 3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
79 Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
80 Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
81 misinterpretation by any end user.
82 4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
83 transparently to the maximum extent possible in their national and regional publications. Any divergence between
84 any IEC Publication and the corresponding national or regional publication shall be clearly indicated in the latter.
85 5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity
86 assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any
87 services carried out by independent certification bodies.
88 6) All users should ensure that they have the latest edition of this publication.
89 7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and
90 members of its technical committees and IEC National Committees for any personal injury, property damage or
91 other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and
92 expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC
93 Publications.
94 8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is
95 indispensable for the correct application of this publication.
96 9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of patent
97 rights. IEC shall not be held responsible for identifying any or all such patent rights.
98 International Standard IEC 61960-4 has been prepared by subcommittee 21A: Secondary cells
99 and batteries containing alkaline or other non-acid electrolytes, of IEC technical committee 21:
100 Secondary cells and batteries.
101 This second edition cancels and replaces the first edition published in 2020. This edition
102 constitutes a technical revision.
103 This edition includes the following significant technical changes with respect to the previous
104 edition:
105 a) added an annex to standardize requirements for secondary lithium watch batteries;
106 b) added new chemistries;
107 c) added a table to standardize dimensions and size codes for secondary lithium watch
108 batteries;
109 d) modified marking requirements;
