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;
b) importation of the dimensional stability from 60086-1;
c) reordering category 1, 5 and 6 batteries by volume;

d) addition of cochlear implant tests and a new zinc air hearing aid battery type;

e) modification of PR70 hearing aid tests;
f) addition of a compliance checklist annex (Annex E);
---------------------- Page: 7 ----------------------
– 6 – IEC 60086-2:2021 © IEC 2021
g) modifications to the LR1/R1 tests;

h) addition of new specifications for 8LR932, CR1632, CR1225, CR2477, 6AS6P, 6AS6S,

6PS6P, 6PS6S, 6PS4P, 6PS4S, 5PR175/172, 6PR225/155, AS4, AS6, AS8, AS10, AS12,

The text of this International Standard is based on the following documents:
FDIS Report on voting
35/1466/FDIS 35/1468/RVD

Full information on the voting for the approval of this International Standard 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/standardsdev/publications.

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 document will remain unchanged until the

stability date indicated on the IEC website under "http://webstore.iec.ch" in the data related to

the specific document. At this date, the document 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.
