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) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of patent
rights. IEC shall not be held responsible for identifying any or all such patent rights.
International Standard IEC 60086-2 has been prepared by IEC technical committee 35: Primary
cells and batteries.
This fourteenth edition cancels and replaces the thirteenth edition published in 2015. This
edition constitutes a technical revision.

INTRODUCTION
The technical content of this part of IEC 60086 provides physical dimensions, discharge test
conditions and discharge performance requirements. IEC 60086-2 complements the general
information and requirements of IEC 60086-1.
This part was prepared to benefit primary battery users, device designers and battery
manufacturers by furnishing the specifics of form, fit and function for individual standardized
primary cells and batteries. Over the years, this part has been changed to improve its contents
and may again be revised in due course in the light of comments made by national committees
and experts on the basis of practical experience and changing technology.
This current revision is the result of a reformatting initiative, as well as some content changes,
aimed at making this part more user-friendly, less ambiguous, and, from a cross reference basis,
fully harmonized with other parts of IEC 60086.
NOTE Safety information is available in IEC 60086-4, IEC 60086-5 and IEC 62281.

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:
a) Category 1 batteries:

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) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of patent
rights. IEC shall not be held responsible for identifying any or all such patent rights.
International Standard IEC 60086-2 has been prepared by IEC technical committee 35: Primary
cells and batteries.
This fourteenth edition cancels and replaces the thirteenth edition published in 2015. This
edition constitutes a technical revision.
This edition includes the following significant technical changes with respect to the previous
edition:
a) clarification and distinct separation of the terms used for coin (lithium button) and button
cells and batteries;

INTRODUCTION
The technical content of this part of IEC 60086 provides physical dimensions, discharge test
conditions and discharge performance requirements. IEC 60086-2 complements the general
information and requirements of IEC 60086-1.
This part was prepared to benefit primary battery users, device designers and battery
manufacturers by furnishing the specifics of form, fit and function for individual standardized
primary cells and batteries. Over the years, this part has been changed to improve its contents
and may again be revised in due course in the light of comments made by national committees
and experts on the basis of practical experience and changing technology.
This current revision is the result of a reformatting initiative, as well as some content changes,
aimed at making this part more user-friendly, less ambiguous, and, from a cross reference basis,
fully harmonized with other parts of IEC 60086.
