LEAD-ACID STARTER BATTERIES –
Part 4: Dimensions of batteries for heavy vehicles

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.
This redline version of the official IEC Standard allows the user to identify the changes made to
the previous edition IEC 60095-4:2008. A vertical bar appears in the margin wherever a change
has been made. Additions are in green text, deletions are in strikethrough red text.

4.3 Marking of plastic material
Batteries are universally marked to identify the plastic material. Various marking schemes
exist around the world in line with local regulations. However all schemes identify the plastic
material by embossing or indenting it into the battery housing. The material content shall be in
accordance with ISO 1043-1.
”PP/PE“ or ”PP“ is used as the marking for types of plastic materials.
Some materials also include the recycling symbol (ISO 7000-1135) as shown in Figure 2.

Figure 2 – Marking of polypropylene

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 5 mm and 7 mm.
An example for this marking is shown in Figure 2.

Figure 2 – Marking of polypropylene-polyethylene copolymer battery components
Producers are encouraged to consult the regulations of the target market.

It is permissible to use the number coding 7 or 07 for PP/PE and the addition of "other" to
cover additives to the plastic material.
4.4 Dimensions and design
All dimensions are in millimetres and sometime also in inches when mentioned in brackets.
Details of the design that are not indicated in the generic drawings have to be chosen
appropriately. The illustrations in this document, especially those of the design of the lids,
