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 60086-4 has been prepared by IEC technical committee 35:
Primary cells and batteries.
This second edition cancels and replaces the first edition, published in 1996, and constitutes
a technical revision.
The text of this standard is based on the following documents:

FDIS Report on voting
35/1114/FDIS 35/1125/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 3.
Annexes A, B and C are for information only.

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

– Part 1: General
– Part 2: Specification sheets

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

The committee has decided that the contents of this publication 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 publication may be issued at a later date.

INTRODUCTION
The concept of safety is closely related to safeguarding the integrity of people and property.

This standard specifies requirements and tests for lithium batteries and has been prepared in
accordance with ISO/IEC guidelines, taking into account all relevant national and international
standards which apply.
Lithium batteries are different from conventional primary batteries using aqueous electrolyte
in that they contain flammable materials.

Consequently, it is important to take safety precautions very carefully during design,
production, distribution, use, and disposal of lithium batteries. Based on such special
characteristics, lithium batteries for consumer applications were initially small in size and had
low power output. There were also lithium batteries with high power output which were used
for special industrial applications and were characterized as being “technician replaceable”.
The first edition of IEC 60086-4 (1996) was drafted to accommodate the above situation.
However, from around the end of the 1980s, lithium batteries with high power output have
started to be widely used in the consumer replacement market, mainly as a power source in
camera applications.
Since the demand for such lithium batteries with high power output has significantly increased
in recent years, various manufacturers have started to produce these types of lithium
batteries. As a consequence of this situation, the safety aspects for lithium batteries with high
power output have been included in this second edition of IEC 60086-4.
Safety is a balance between freedom from hazard and other requirements to be met by the
product. There can be no absolute safety. Even at the highest level of safety, the product can
only be relatively safe. In this respect, decision-making is based on risk evaluation and safety
judgement.
As safety will pose different problems, it is impossible to provide a set of precise provisions
and recommendations that will apply in every case. However, this standard, when followed on
a judicious “use when applicable” basis, will provide reasonably consistent standards for
safety.

1 Scope
This International Standard specifies tests and requirements for primary lithium batteries to

ensure their safe operation under intended use and reasonably foreseeable misuse.

2 Normative reference
The following normative documents contain provisions which, through reference in this text,
constitute provisions of this International Standard. For dated references, subsequent
amendments to, or revisions of, any of these publications do not apply. However, parties to
agreements based on this International Standard are encouraged to investigate the possibility
of applying the most recent edition 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.
