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 provides no marking procedure to indicate its approval and cannot be rendered responsible for any
equipment declared to be in conformity with an IEC Publication.
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 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 standard is based on the following documents:
FDIS Report on voting
21A/391/FDIS 21A/396/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.

2008. At this date the publication will be
• reconfirmed;
• withdrawn;

SECONDARY CELLS AND BATTERIES CONTAINING

SECONDARY LITHIUM CELLS AND BATTERIES
FOR PORTABLE APPLICATIONS
1 Scope
This International Standard specifies performance tests, designations, markings, dimensions
and other requirements for secondary lithium single cells and batteries for portable
applications.
The objective of this standard 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.
This standard 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.
This standard 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 end-of-discharge voltage during
discharge. Users of secondary lithium cells and batteries are requested to consult the
manufacturer for advice.
2 Normative references

dated references, only the edition cited applies. For undated references, the latest edition of

3 Terms and definitions
For the purpose of this International Standard, the definitions contained in IEC 60050-486 and
the following apply.
3.1
charge (capacity) recovery
capacity that a cell or battery can deliver after the charge following the charge retention test
according to 3.2
3.2
charge (capacity) retention
capacity that a cell or battery can deliver after storage, at a specific temperature, for a specific
time without subsequent recharging as a percentage of the rated capacity
3.3
final voltage
end-of-discharge voltage
specified closed circuit voltage at which a discharge of a cell or battery is terminated
3.4
nominal voltage:
suitable approximate value of voltage used to identify the voltage of a cell or battery
NOTE 1 The nominal voltages of secondary lithium cells are given in Table 1.
NOTE 2 The nominal voltage of a battery of n series connected cells is equal to n times the nominal voltage of a
single cell.
3.5
rated capacity
quantity of electricity C Ah (ampere-hours) declared by the manufacturer which a single cell or
5
battery can deliver during a 5-h period, when charged, stored and discharged under the
conditions specified in 7.2.1
3.6
secondary lithium battery
unit which incorporates one or more secondary lithium cells and which is ready for use. It
incorporates adequate housing and a terminal arrangement and may have electronic control
devices
3.7
secondary lithium cell
secondary single cell whose electrical energy is derived from the oxidation and the reduction of
lithium. It is not ready for use in an application because it is not yet fitted with its final housing,
terminal arrangement and electronic control device
