12 V LITHIUM-ION SECONDARY BATTERIES FOR
AUTOMOTIVE STARTING, LIGHTING, IGNITION (SLI)
APPLICATIONS AND AUXILIARY PURPOSES –

Part 1: General requirements and methods of test

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) IEC draws attention to the possibility that the implementation of this document may involve the use of (a)
patent(s). IEC takes no position concerning the evidence, validity or applicability of any claimed patent rights in
respect thereof. As of the date of publication of this document, IEC had not received notice of (a) patent(s), which
may be required to implement this document. However, implementers are cautioned that this may not represent
the latest information, which may be obtained from the patent database available at https://patents.iec.ch. IEC
shall not be held responsible for identifying any or all such patent rights.
IEC 63118-1 has been prepared by IEC technical committee 21: Secondary cells and batteries.
It is an International Standard.
The text of this International Standard is based on the following documents:

described in greater detail at www.iec.ch/publications.
A list of all parts in the IEC 63118 series, published under the general title 12 V lithium-ion
secondary batteries for automotive starting, lighting, ignition (SLI) applications and auxiliary
purposes, 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 webstore.iec.ch in the data related to the
specific document. At this date, the document will be

12 V LITHIUM-ION SECONDARY BATTERIES FOR
AUTOMOTIVE STARTING, LIGHTING, IGNITION (SLI)
APPLICATIONS AND AUXILIARY PURPOSES –

Part 1: General requirements and methods of test

1 Scope
This part of IEC 63118 specifies the general tests and requirements for the performance of
lithium secondary batteries with a nominal voltage of 12 V permanently installed in road vehicles
not for propulsion. The replacement of secondary batteries permanently installed in road
vehicles not for propulsion is covered by this document.
The following are typical applications that utilize the batteries under the scope of this document:
power source for the starting of internal combustion engines, lighting, stop and start function,
on-board auxiliary equipment and energy absorption for regeneration from braking.
The batteries primarily used for propulsion of electric vehicles (EV) including battery electric
vehicles (BEV), hybrid electric vehicles (HEV), and plug-in hybrid electric vehicles (PHEV) are
not covered by this document.
This document includes:
• electrical characteristics tests methods and requirements;
• a life duration tests method.
This document does not include:
• dimensions;
• the system communication protocol;
• safety aspects.
NOTE The safety aspects of the batteries are covered by IEC 63057.
