Part 2: Physical and electrical specifications

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 thirteenth edition cancels and replaces the twelfth edition (2011) and constitutes a
technical revision.
Significant changes from the previous edition are test changes to battery types R03, LR03, R6,
LR6, PR70, PR41, PR48, 6F22, 6LR61, 6LP3146 4LR25-2, R14, LR14, R20, LR20, CR2025,
and CR2032, adding the 5AR40 back into the standard, addition of common designations,
addition of two new battery types FR14505 and FR10G445, deletion of battery types LR53,
R40, 2EP3863, 6F100, and general editorial changes.

The text of this standard is based on the following documents:
FDIS Report on voting
35/1350/FDIS 35/1352/RVD
Full information on the voting for the approval of this standard can be found in the report on
voting indicated in the above table.
This publication has been drafted in accordance with the ISO/IEC Directives, Part 2.
A list of all parts in the IEC 60086 series, under the general title Primary batteries, can be
found on the IEC website.
The committee has decided that the contents of this publication will remain unchanged until
the stability date indicated on the IEC website under "http://webstore.iec.ch" in the data
related to the specific publication. At this date, the publication will be
• reconfirmed,
• withdrawn,
• replaced by a revised edition, or
• amended.
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.
