SECONDARY CELLS AND BATTERIES CONTAINING ALKALINE
OR OTHER NON-ACID ELECTROLYTES – SECONDARY LITHIUM CELLS
AND BATTERIES FOR PORTABLE APPLICATIONS –

Part 3: Prismatic and cylindrical lithium secondary cells,
and batteries made from them

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 61960-3 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 first edition cancels and replaces the second edition of IEC 61960 published in 2011. It is
a technical revision.
This edition includes the following significant technical changes with respect to the previous
edition:
• adding definition of portable applications (Scope),
• update of examples of cells (Table 1 and 2),

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

• adding “Dimensions of the cell with a laminate film case” (Annex A),
• adding “Capacity after storage” (from the date of manufacture) (Annex B).
The text of this standard is based on the following documents:
FDIS Report on voting
21A/618/FDIS 21A/625/RVD

Full information on the voting for the approval of this International Standard can be found in
the report on voting indicated in the above table.
This document has been drafted in accordance with the ISO/IEC Directives, Part 2.
A list of all parts in the IEC 61960 series, published under the general title Secondary cells
and batteries containing alkaline or other non-acid electrolytes – Secondary lithium cells and
batteries for portable applications, can be found on the IEC website.
The committee has decided that the contents of this document will remain unchanged until the
stability date indicated on the IEC website under "http://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.

SECONDARY CELLS AND BATTERIES CONTAINING ALKALINE
OR OTHER NON-ACID ELECTROLYTES – SECONDARY LITHIUM CELLS
AND BATTERIES FOR PORTABLE APPLICATIONS –

Part 3: Prismatic and cylindrical lithium secondary cells,
and batteries made from them



1 Scope
This part of IEC 61960 specifies performance tests, designations, markings, dimensions and
other requirements for secondary lithium single cells and batteries for portable applications.
The objective of this document is to provide the purchasers and users of secondary lithium
cells and batteries with a set of criteria with which they can judge the performance of
secondary lithium cells and batteries offered by various manufacturers.
Portable applications comprise hand-held equipment, transportable equipment and movable
equipment.
Examples of the main uses are shown below:
a) hand-held equipment: smartphone, tablet PCs, audio/video players, and similar
equipment;
b) transportable equipment: notebook computers, CD players, and similar equipment;
c) movable equipment
• 18 kg or less in mass and not fixed in place, or
• provided with wheels, castors, or other means to facilitate movement by an ordinary
person as required to perform its intended use,
• power tools, power assisted cycles, business-use video cameras, and similar
equipment.
NOTE 1 All applications using batteries whose nominal voltages are equal to or over the hazardous voltage
of 60 V DC are excluded.
NOTE 2 EESS (Electrical Energy Storage Systems) and UPS, which use batteries over 500 Wh of electric energy
are excluded.
NOTE 3 Self-propelled vehicles are excluded.
This document defines a minimum required level of performance and a standardized
methodology by which testing is performed and the results of this testing reported to the user.
Hence, users will be able to establish the viability of commercially available cells and
batteries via the declared specification and thus be able to select the cell or battery best
suited for their intended application. The end user can handle only batteries which have
completely fulfilled all the requirements of this document and others concerning safety such
as IEC 62133-2.
This document covers secondary lithium cells and batteries with a range of chemistries. Each
electrochemical couple has a characteristic voltage range over which it releases its electrical
capacity, a characteristic nominal voltage and a characteristic final voltage during discharge.
Users of secondary lithium cells and batteries are requested to consult the manufacturer for
advice.
