PRIMARY BATTERIES –
Part 2: Physical and electrical specifications

FOREWORD
1) The IEC (International Electrotechnical Commission) is a worldwide organization for standardization comprising
all national electrotechnical committees (IEC National Committees). The object of the 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, the IEC publishes International Standards. 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. The 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 the 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 National Committees.
3) The documents produced have the form of recommendations for international use and are published in the form
of standards, technical specifications, technical reports or guides and they are accepted by the National
Committees in that sense.
4) In order to promote international unification, IEC National Committees undertake to apply IEC International
Standards transparently to the maximum extent possible in their national and regional standards. Any
divergence between the IEC Standard and the corresponding national or regional standard shall be clearly
indicated in the latter.
5) The IEC provides no marking procedure to indicate its approval and cannot be rendered responsible for any
equipment declared to be in conformity with one of its standards.
6) Attention is drawn to the possibility that some of the elements of this International Standard may be the subject
of patent rights. The 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 consolidated version of IEC 60086-2 is based on the tenth edition (2000) [documents
35/1136/FDIS and 35/1147/RVD], and its amendment 1 (2001) [documents 35/1157/FDIS
and 35/1163/RVD].
It bears the edition number 10.1.
A vertical line in the margin shows where the base publication has been modified by
amendment 1.
This publication has been drafted in accordance with the ISO/IEC Directives, Part 3.
Annexes A, B and C are for information only.

– 4 – 60086-2 © IEC:2000+A1:2001(E)

IEC 60086 consists of the following parts under the general title: Primary batteries

– Part 1: General
– Part 2: Physical and electrical specifications

– Part 3: Watch batteries
– Part 4: Safety of lithium batteries

– Part 5: Safety of batteries with aqueous electrolyte

The committee has decided that the contents of the base publication and its amendment will
remain unchanged until 2002. At this date, the publication will be
• reconfirmed;
• withdrawn;
• replaced by a revised edition, or
• amended.
A bilingual version of this standard may be issued at a later date.

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 through provision of specification sheets for

primary cells and batteries.
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 as been removed from IEC 60086-1, and is now available in IEC 60086-4 and
IEC 60086-5.

2 Normative references
The following normative documents contain provisions which, through reference in this text,
constitute provisions of this part of IEC 60086. For dated references, subsequent amend-
ments to, or revisions of, any of these publications do not apply. However, parties to
agreements based on this part of IEC 60086 are encouraged to investigate the possibility of
applying the most recent editions of the normative documents indicated below. For undated
references, the latest edition of the normative document referred to applies. Members of IEC
and ISO maintain registers of currently valid International Standards.
