AMENDMENT 1
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 document may be the subject of patent
rights. IEC shall not be held responsible for identifying any or all such patent rights.
Amendment 1 to IEC 62133-2:2017 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.
The text of this Amendment is based on the following documents:
FDIS Report on voting
21A/760/FDIS 21A/729B/RVD
Full information on the voting for its approval can be found in the report on voting indicated in
the above table.
© IEC 2021
The language used for the development of this Amendment 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/.
The committee has decided that the contents of this document will remain unchanged until the
stability date indicated on the IEC website under 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.

7.1.2 Second procedure
Replace the existing second paragraph and Table 2 with the following:
After stabilization for 1 h to 4 h at an ambient temperature of the highest test temperature and
the lowest test temperature, respectively, as specified in Table 2, cells are charged by using
the upper limit charging voltage and maximum charging current, until the charging current is
reduced to 0,05 I A, using a constant current to constant voltage charging method.
t
NOTE The voltage and current can vary depending upon the temperature range (e.g. between T and T or between
2 3
T and T of Figure A.1).
1 4
Stabilization time within the specified time range should allow for thermal equilibrium to be
reached where possible.

7.3.5 Crush (cells)
b) Test
Replace the first paragraph of list item b) with the following:
Each fully charged cell, charged according to the second procedure in 7.1.2, is immediately
transferred and crushed between two flat surfaces in an ambient temperature. The force for
the crushing is applied by a device exerting a force of 13 kN ± 0,78 kN. Once the maximum
force has been applied, or an abrupt voltage drop of one-third of the original voltage has
been obtained, the force is released.

7.3.6 Over-charging of battery
Replace the existing list item a) with the following list item a):
a) Requirements
Battery overcharge protection circuitry, if provided in the battery, shall be capable of protecting
the cells to prevent fire or explosion.

7.3.9 Design evaluation – Forced internal short-circuit (cells)
Replace the existing Table 5 with the following new Table 5:

(informative)
Component standards references
Replace the existing content of Annex F with the following:
Components relied upon for safety of the battery should comply with their appropriate
component standard if applicable. The list in Table F.1 is not considered a comprehensive list
of all potential component safety standards that may apply. In addition, country and regional
component safety standards as well as international component safety standards may be
considered if they are suitable for the component in question, and the component is being used
