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 62620:2014 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:
Draft Report on voting
21A/795/CDV 21A/812/RVC
Full information on the voting for its approval can be found in the report on voting indicated in
the above table.

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

Replace existing Note 1 with the following new Note 1:
NOTE 1 These types of cells are typically but not exclusively used for the following discharge rates at +25 °C:
• E up to 0,5 I A,
t
• M up to 3,5 I A,
t
• H above 3,5 I A.

Replace existing Example 1 with the following new Example 1:
EXAMPLE 1 ---ICP200/150/150[7S]E/0+50/75 would designate a battery composed of 7S connected prismatic Li-ion
secondary cells, with a cobalt-based positive electrode. Its cell maximum thickness is between 199 mm and 200 mm,
its cell maximum width is between 149 mm and 150 mm, and its cell overall height is between 149 mm and 150 mm.
The battery is designed for low discharge rate over a long period. Its low temperature grade is 0 °C. Its high
temperature grade is +50 °C. Its capacity after 500 cycles to rated capacity is between 75 % and 79 %.
6.3.2 Discharge performance at low temperature
Replace the existing seventh paragraph with the following new seventh paragraph:
The cell or battery's low temperature grade TL can be declared at 10 °C intervals, such as
+10 °C, 0 °C, −10 °C and −20 °C. The declared temperature should be in the range of the target
test temperature and target test temperature plus 10 °C. For example, if the test is performed
at −27 °C, the declared temperature should be −20 °C. The temperature grade is the highest
temperature among the tests for discharge rate type M and H. For example, if an "H" type cell
has a discharge capacity higher than 70 % of the rated capacity: at −30 °C with 0,2 I A, at
t
−20 °C, with 1,0 I A and at −10 °C with 5,0 I A, the temperature grade is judged as "−10 °C".
t t
7.3.2 Electrical tests
Replace the existing text of 7.3.2.1 with the following:
7.3.2.1 The manufacturer shall declare the rated capacity (C Ah) of the cell, cell block or
n
battery based on its performance under the conditions specified in 6.3.1 and Table 6.
