SECONDARY CELLS AND BATTERIES CONTAINING ALKALINE
OR OTHER NON-ACID ELECTROLYTES –

SAFETY REQUIREMENTS FOR PORTABLE SEALED
SECONDARY CELLS, AND FOR BATTERIES MADE FROM THEM,
FOR USE IN PORTABLE APPLICATIONS


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 62133 has been prepared by subcommittee 21A: Secondary cells
and batteries containing alkaline or other non-acid electrolytes, of IEC technical committee 21:
Secondary cells and batteries.
This second edition cancels and replaces the first edition published in 2002. It constitutes a
technical revision.
This edition includes the following significant technical changes with respect to the previous
edition:
– update of assembly of cells into batteries (5.5);
– addition of design recommendations for lithium system only (5.6.2);
– separation of nickel systems and lithium systems (Clause 6);

---------------------- Page: 10 ----------------------

SIST EN 62133:2013
62133 © IEC:2012 – 5 –
– addition of specific requirements and tests for lithium systems (Clause 8);
– addition of charging of secondary lithium-ion cells for safe use (Annex A).
The text of this standard is based on the following documents:
FDIS Report on voting
21A/503/FDIS 21A/509/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.
The following difference exists in the countries indicated below:
Subclause 8.3.9: Design evaluation – Forced internal short circuit only applies to Korea,
Japan, Switzerland and France.
The committee has decided that the contents of this publication will remain unchanged until
the stability date indicated on the IEC web site 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.


IMPORTANT – The 'colour inside' logo on the cover page of this publication
indicates that it contains colours which are considered to be useful for the correct
understanding of its contents. Users should therefore print this document using a
colour printer.

5 General safety considerations
5.1 General
The safety of secondary cells and batteries requires the consideration of two sets of applied
conditions:
• intended use;
• reasonably foreseeable misuse.
Cells and batteries shall be so designed and constructed that they are safe under conditions
of both intended use and reasonably foreseeable misuse. It is expected that cells or batteries
subjected to misuse may fail to function following such experience. They shall not however
present significant hazards. It may also be expected that cells and batteries subjected to
intended use shall not only be safe but shall continue to be functional in all respects.
Potential hazards which are the subject of this standard are:
