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.

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.
