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 60254-2 has been prepared by committee 21: Secondary cells and
batteries
This fourth edition cancels and replaces the third edition published in 1997 and its
Amendment 1 (2000). It constitutes a technical revision. The main modification concerns the
introduction of new dimensions.
The text of this standard is based on the following documents:
FDIS Report on voting
21/668/FDIS 21/670/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.

A list of all parts of the IEC 60254 series, published under the general title Lead-acid traction
batteries, can be found on the IEC website.
The committee has decided that the contents of this publication will remain unchanged until
the maintenance result date indicated on the IEC web site under "http://webstore.iec.ch" in
the data related to the specific publication. At this date, the publication will be
• reconfirmed,
• withdrawn,
• replaced by a revised edition, or
• amended.

LEAD-ACID TRACTION BATTERIES –

Part 2: Dimensions of cells and terminals
and marking of polarity on cells

1 Scope and object
This part of IEC 60254 is applicable to lead-acid traction batteries used as power sources for
electric propulsion.
The object of the present standard is to specify:
– the maximum external (overall) dimensions of traction battery cells, that is, the width, the
height and the length;
– the form of the marking of traction battery cell polarity and dimensions of corresponding
symbols;
– the basic dimensions of some commonly used traction battery terminals designed to
connect output cables to the battery;
– the dimensions of cells commonly used in Asia and North America.
2 Normative references
The following referenced documents are indispensable for the application of this document.
For dated references, only the edition cited applies. For undated references, the latest edition
of the referenced document (including any amendments) applies.
IEC 60417, Graphical symbols for use on equipment
3 Main dimensions of traction battery cells
3.1 Standard series
Traction battery cells in accordance with this standard shall belong to one of the following two
dimensional series determined by the width:
E (narrow) L (wide)
3.2 External dimensions
3.2.1 The external (overall) dimensions of traction battery cells are represented by the
following symbols:
b width (dimension parallel to the surface of the plates);
h height (including lid, vent plugs and terminals, but without output cable);
l length (dimension perpendicular to the surface of the plates).
3.2.2 The dimensions of traction battery cells in accordance with this standard shall
correspond to those of Table 1.
