GENERAL PURPOSE LEAD-ACID BATTERIES
(VALVE-REGULATED TYPES) –

Part 1: General requirements, functional characteristics –
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) 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 61056-1 has been prepared by IEC technical committee 21:
Secondary cells and batteries.
This third edition cancels and replaces the second edition of IEC 61056-1 published in 2002.
It constitutes a technical revision.
The main changes consist in adding new battery designations and an update of the
requirements like the one concerning the marking.

GENERAL PURPOSE LEAD-ACID BATTERIES
(VALVE-REGULATED TYPES) –

Part 1: General requirements, functional characteristics –
Methods of test



1 Scope
This Part of IEC 61056 specifies the general requirements, functional characteristics and
methods of test for all general purpose lead-acid cells and batteries of the valve-regulated
type :
• for either cyclic or float charge application;
• in portable equipment, for instance, incorporated in tools, toys, or in static emergency, or
uninterruptible power supply and general power supplies.
The cells of this kind of lead-acid battery may either have flat-plate electrodes in prismatic
containers or have spirally wound pairs of electrodes in cylindrical containers. The sulphuric
acid in these cells is immobilized between the electrodes either by absorption in a micro-
porous structure or in a gelled form.
NOTE The dimensions, terminals and marking of the lead-acid cells and batteries which are applied by this
standard are given in IEC 61056-2.
This part of IEC 61056 does not apply for example to lead-acid cells and batteries used for
• vehicle engine starting applications (IEC 60095 series),
• traction applications (IEC 60254 series), or
• stationary applications (IEC 60896 series).
Conformance to this standard requires that statements and claims of basic performance data
by the manufacturer correspond to these test procedures. The tests may also be used for type
qualification.
