LEAD-ACID STARTER BATTERIES –
Part 2: Dimensions of batteries and
dimensions and marking of terminals

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 60095-2 has been prepared by IEC technical committee 21:
Secondary cells and batteries.
This fifth edition cancels and replaces the fourth edition published in 2009. This edition
constitutes a technical revision.
This edition includes the following significant technical changes with respect to the previous
edition:
a) update of the dimensions of batteries:
• in Europe according to the last version of the European standard;
• in USA with figures updated;
• in Asia with one type of Japanese battery removed.

batteries, 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

4 General requirements
4.1 General
The specifications of Clause 4 are common to all starter batteries according to this document.
4.2 Marking
4.2.1 Safety labelling
The batteries shall bear the six coloured safety symbols in accordance with 6.1.6 of
IEC 60095-1:2018.
4.2.2 Marking of the polarity of terminals
4.2.2.1 General
The batteries shall carry the marking of polarity, at least of the positive terminal.
4.2.2.2 Marking of positive terminals
This marking shall take the form of the symbol "+" either on the upper surface of the positive
terminal or on the lid adjacent to the positive terminal.
4.2.2.3 Marking of negative terminals
This marking shall take the form of the symbol "–" either on the upper surface of the negative
terminal or on the lid adjacent to the negative terminal.
4.2.2.4 Design and dimensions of marking of terminals
The symbols used for marking the terminals shall be in accordance with
IEC 60417-5005:2012-10 for the positive and IEC 60417-5006:2012-10 for the negative
polarity.
The dimensions of the marking shall be according to Figure 1.
Dimensions in millimetres
Figure 1 – Marking of polarity
The polarity symbols may be either indented or embossed by (0,4 ± 0,1) mm.
As an alternative, the wordings "POS" and "NEG" are permitted for the North American market
only.
4.3 Recycling
4.3.1 Recycling of lead
The batteries shall be marked with the symbols for recycling and separate collection according
to IEC 60095-1.
4.3.2 Recycling of plastic material
Injection moulded battery components need to be marked according to ISO 11469 and
ISO 1043-1. The marking shall be placed on the bottom of the battery container or on one short
side near the ledge.
According to ISO 11469 and ISO 1043-1 the minimum marking for polypropylene-polyethylene
copolymer is >PP< or >PP/PE<.
In addition it is possible to show the recycling symbol with number 7 (Unicode character
'RECYCLING SYMBOL FOR TYPE-7 PLASTICS' (U+2679) according to ISO/IEC 10646) and
the term "Other".
The recommended thickness is (0,3 ± 0,1) mm. The height of the marking characters shall be
between 3 mm and 7 mm.
An example for this marking is shown in Figure 2.
