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

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
FR10G445, FR14505
• Category 2: Round batteries according to Figure 4

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.
IEC 60086-2-2 has been prepared by IEC technical committee 35: Primary cells and batteries.
It is an International Standard.
This first edition cancels and replaces the fourteenth edition of IEC 60086-2 published in 2021.
This edition constitutes a technical revision.
This edition includes the following significant technical changes with respect to the previous
edition:
a) the physical and electrical specifications of IEC 60086-2:2021 were divided into two new
standards based on their electrolyte types. IEC 60086-2-1 provides specifications for
standardized primary batteries containing aqueous electrolyte. IEC 60086-2-2 covers
specifications for standardized lithium-based primary batteries;
b) maximum open circuit voltage of FR10G445 and FR14505 was changed from 1,83 to 1,90 V;
c) load of digital audio test for FR10G445 was changed from 50 mA to 75 mA and MAD was
modified;
d) portable lighting test was added for FR10G445;
e) motor/toy and radio /clock /remote control test was added for FR14505;
f) in Clause 3, terms were reordered according to their functions: basic terms, electrochemical
systems, electrical characteristics and specifications;
g) Annex D for common designation of IEC 60086-2:2021 was moved to IEC 60086-1:2026, as
Annex H;
h) Annex E for Compliance checklist of IEC 60086-2:2021 was removed and merged into
Annex J of IEC 60086-1:2026.
The text of this International Standard is based on the following documents:
Draft Report on voting
35/1592/FDIS 35/1598/RVD
Full information on the voting for its approval can be found in the report on voting indicated in
the above table.
The language used for the development of this International Standard is English.
This document was drafted in accordance with ISO/IEC Directives, Part 2, and developed in
accordance with ISO/IEC Directives, Part 1 and ISO/IEC Directives, IEC Supplement, available
at www.iec.ch/members_experts/refdocs. The main document types developed by IEC are
described in greater detail at www.iec.ch/publications.
