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

[SOURCE: IEC 60050-482:2004, 482-02-22, modified – “conductive part of a device, electric
circuit or electric network, provided” replaced by to “conductive parts of a battery providing” and
“device, electric circuit or electric network to one or more external conductor” replaced by “an
external circuit”]
4 Battery dimensions – Symbols
The symbols used to denote the various dimensions are as follows:
maximum overall height of the battery;
h
h minimum distance between the flats of the positive and negative contacts;
h minimum projection of the flat positive contact;
h maximum recess of the negative flat contact surface;
h minimum projection of the flat negative contact;
d maximum and minimum diameters of the battery;
d minimum diameter of the flat positive contact;
d maximum diameter of the positive contact within the specified projection height;
d minimum diameter of the flat negative contact;
d maximum diameter of the negative contact within the specified projection height;
d minimum outer diameter of the negative flat contact surface;
d maximum inner diameter of the negative flat contact surface;
øP concentricity of the positive contact.
5 Dimensional stability
Refer to IEC 60086-1 for dimensional stability.
6 Validity of testing
Portable primary batteries shall be subjected to the tests, as required in the IEC 60086 series.
Testing remains valid until a design change or requirement revision has been made. Retesting
is required when:
a) a battery specification changes by more than 0,1 g or 20 % mass, whichever is greater, for
the cathode, anode or electrolyte;
b) a battery specification changes that would lead to a failure of any of the tests;
c) there is an addition of new tests or requirements; or
d) there is a requirement change that would lead to a failure on any of the tests.
7 Constitution of the battery specification tables
– Batteries are categorized into several groups according to their shapes.
– In each category, batteries having the same shape but belonging to a different
electrochemical system are grouped together and shown in succession.
– Batteries are always listed in ascending order of nominal voltage and, within each nominal
voltage, in ascending order of volume.
– One common shape drawing of these batteries which fall in the same group is exhibited.
– Designation, nominal voltage, dimensions, discharge conditions, minimum average duration
and application for these batteries which fall into the same group are summarized in one
table.
– When a drawing represents only one type of battery, the dimensions of the relevant battery
may be directly shown on the drawing.
– Batteries are categorized into the following groups:
• Category 1: Round batteries according to Figure 1

INTERNATIONAL ELECTROTECHNICAL COMMISSION
____________
Primary batteries -
Part 2-1: Physical and electrical specifications
of batteries with aqueous electrolyte

FOREWORD
1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
all national electrotechnical committees (IEC National Committees). The object of IEC is to promote international
co-operation on all questions concerning standardization in the electrical and electronic fields. To this end and
in addition to other activities, IEC publishes International Standards, Technical Specifications, Technical Reports,
Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC Publication(s)”). Their
preparation is entrusted to technical committees; any IEC National Committee interested in the subject dealt with
may participate in this preparatory work. International, governmental and non-governmental organizations liaising
with the IEC also participate in this preparation. IEC collaborates closely with the International Organization for
Standardization (ISO) in accordance with conditions determined by agreement between the two organizations.
2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
consensus of opinion on the relevant subjects since each technical committee has representation from all
interested IEC National Committees.
3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
misinterpretation by any end user.
4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
transparently to the maximum extent possible in their national and regional publications. Any divergence between
any IEC Publication and the corresponding national or regional publication shall be clearly indicated in the latter.
5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity
assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any
services carried out by independent certification bodies.
6) All users should ensure that they have the latest edition of this publication.
7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and
members of its technical committees and IEC National Committees for any personal injury, property damage or
other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and
expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC
Publications.
8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is
indispensable for the correct application of this publication.
9) IEC draws attention to the possibility that the implementation of this document may involve the use of (a)
patent(s). IEC takes no position concerning the evidence, validity or applicability of any claimed patent rights in
respect thereof. As of the date of publication of this document, IEC had not received notice of (a) patent(s), which
may be required to implement this document. However, implementers are cautioned that this may not represent
the latest information, which may be obtained from the patent database available at https://patents.iec.ch. IEC
shall not be held responsible for identifying any or all such patent rights.
This commented version (CMV) of the official standard IEC 60086-2-1:2026 edition 1.0 provides

AVANT-PROPOS
1) La Commission Électrotechnique Internationale (IEC) est une organisation mondiale de normalisation composée
de l’ensemble des comités électrotechniques nationaux (Comités nationaux de l’IEC). L’IEC a pour objet de
favoriser la coopération internationale pour toutes les questions de normalisation dans les domaines de
l’électricité et de l’électronique. À cet effet, l’IEC – entre autres activités – publie des Normes internationales,
des Spécifications techniques, des Rapports techniques, des Spécifications accessibles au public (PAS) et des
Guides (ci-après dénommés "Publication(s) de l’IEC"). Leur élaboration est confiée à des comités d’études,
aux travaux desquels tout Comité national intéressé par le sujet traité peut participer. Les organisations
internationales, gouvernementales et non gouvernementales, en liaison avec l’IEC, participent également aux
travaux. L’IEC collabore étroitement avec l’Organisation Internationale de Normalisation (ISO), selon des
conditions fixées par accord entre les deux organisations.
2) Les décisions ou accords officiels de l’IEC concernant les questions techniques représentent, dans la mesure du
possible, un accord international sur les sujets étudiés, étant donné que les Comités nationaux de l’IEC intéressés
sont représentés dans chaque comité d’études.
3) Les Publications de l’IEC se présentent sous la forme de recommandations internationales et sont agréées
comme telles par les Comités nationaux de l’IEC. Tous les efforts raisonnables sont entrepris afin que l’IEC
s’assure de l’exactitude du contenu technique de ses publications; l’IEC ne peut pas être tenue responsable de
l’éventuelle mauvaise utilisation ou interprétation qui en est faite par un quelconque utilisateur final.
4) Dans le but d’encourager l’uniformité internationale, les Comités nationaux de l’IEC s’engagent, dans toute la
mesure possible, à appliquer de façon transparente les Publications de l’IEC dans leurs publications nationales
et régionales. Toutes divergences entre toutes Publications de l’IEC et toutes publications nationales ou
régionales correspondantes doivent être indiquées en termes clairs dans ces dernières.
5) L’IEC elle-même ne fournit aucune attestation de conformité. Des organismes de certification indépendants
fournissent des services d’évaluation de conformité et, dans certains secteurs, accèdent aux marques de
conformité de l’IEC. L’IEC n’est responsable d’aucun des services effectués par les organismes de certification
indépendants.
6) Tous les utilisateurs doivent s’assurer qu’ils sont en possession de la dernière édition de cette publication.
7) Aucune responsabilité ne doit être imputée à l’IEC, à ses administrateurs, employés, auxiliaires ou mandataires,
y compris ses experts particuliers et les membres de ses comités d’études et des Comités nationaux de l’IEC,
pour tout préjudice causé en cas de dommages corporels et matériels, ou de tout autre dommage de quelque
nature que ce soit, directe ou indirecte, ou pour supporter les coûts (y compris les frais de justice) et les dépenses
découlant de la publication ou de l’utilisation de cette Publication de l’IEC ou de toute autre Publication de l’IEC,
ou au crédit qui lui est accordé.
8) L’attention est attirée sur les références normatives citées dans cette publication. L’utilisation de publications
référencées est obligatoire pour une application correcte de la présente publication.
9) L’IEC attire l’attention sur le fait que la mise en application du présent document peut entraîner l’utilisation d’un
ou de plusieurs brevets. L’IEC ne prend pas position quant à la preuve, à la validité et à l’applicabilité de tout
droit de brevet revendiqué à cet égard. À la date de publication du présent document, l’IEC n’avait pas reçu
notification qu’un ou plusieurs brevets pouvaient être nécessaires à sa mise en application. Toutefois, il y a lieu
d’avertir les responsables de la mise en application du présent document que des informations plus récentes
sont susceptibles de figurer dans la base de données de brevets, disponible à l’adresse https://patents.iec.ch.
L’IEC ne saurait être tenue pour responsable de ne pas avoir identifié de tels droits de brevet.
L’IEC 60086-2-1 a été établie par le comité d’études 35 de l’IEC: Piles. Il s’agit d’une
Norme internationale.
Cette première édition annule et remplace la quatorzième édition de l’IEC 60086-2 parue
en 2021. Cette édition constitue une révision technique.
Cette édition inclut les modifications techniques majeures suivantes par rapport à l’édition
précédente:
a) Les spécifications physiques et électriques de l'IEC 60086-2:2021 ont été divisées en deux
nouvelles normes en fonction du type d'électrolyte. L'IEC 60086-2-1 définit les spécifications
des piles électriques normalisées à électrolyte aqueux. L'IEC 60086-2-2 définit les
spécifications des piles électriques normalisées au lithium;
b) dans l’Article 3, les termes ont été réorganisés selon leurs fonctions: termes de base,
systèmes électrochimiques, caractéristiques électriques et spécifications;
c) ajout des désignations TR03 et TR6 dans la Catégorie 1, Piles rondes;
d) modification de 50 mA à 75 mA de la charge de l’essai audionumérique pour les
désignations LR03, TR03 et R03, et modification de la MAD;
e) ajout de l’essai d’accessoires de toilette pour la désignation LR6, à la place de l’essai
d’application à courant de décharge fort;
f) ajout de l’essai d’application à courant de décharge fort pour la désignation TR6;
g) ajout de l’essai radio/horloge/télécommande pour la désignation R6S;
h) suppression de l’essai CD, audionumérique, jeux sans fil et accessoires pour les
désignations LR6, R6P et R6S;
i) ajout de la désignation commune de 4.5V pour les désignations 3LR12, 3R12P et 3R12S;
j) déplacement dans l’IEC 60086-1:2026, en qualité d’Annexe H, de l’Annexe D de
l’IEC 60086-2:2021 donnant les désignations communes;
k) suppression de l’Annexe E Liste de contrôle de conformité de l’IEC 60086-2:2021 et fusion
avec l’Annexe J de l’IEC 60086-1:2026.

5 Stabilité dimensionnelle
Voir l’IEC 60086-1 pour la stabilité dimensionnelle.
6 Validité des essais
Les piles électriques portables doivent être soumises aux essais, comme exigé dans la série
IEC 60086. Les essais restent valides jusqu’à ce qu’une modification de la conception ou une
révision des exigences ait été effectuée. De nouveaux essais sont exigés lorsque:
a) une spécification de masse de pile varie de plus de 0,1 g ou de 20 %, la plus grande des
valeurs, pour la cathode, l’anode ou l’électrolyte;
b) la modification d’une spécification d’une pile entraînerait un échec des essais;
c) de nouveaux essais ou de nouvelles exigences sont ajoutés; ou
d) la modification d’une exigence entraînerait un échec des essais.
7 Constitution des tableaux de spécifications des piles
– Les piles sont classées en plusieurs groupes suivant leur forme.
– Dans chaque catégorie, les piles qui ont la même forme, mais qui appartiennent à un
système électrochimique différent, sont regroupées et présentées successivement.
– Les piles sont toujours données par ordre croissant de tension nominale et, pour une même
tension nominale, par ordre croissant de volume.
– Un seul dessin représente la forme commune des piles appartenant à un même groupe.
– La désignation, la tension nominale, les dimensions, les conditions de décharge, la durée
moyenne minimale et l’application de ces piles appartenant à un même groupe sont
récapitulées dans un seul tableau.
– Si un dessin ne représente qu’un seul type de pile, les dimensions de cette pile peuvent
être directement représentées sur le dessin.
– Les piles sont classées d’après les groupes suivants:
• piles de catégorie 1: piles rondes conformément à la Figure 1
