Safety requirements for secondary batteries and battery installations - Part 4: Valve-regulated lead-acid batteries for use in portable appliances

This Part of IEC 62485 applies to the safety aspects associated with the accommodation, the
arrangements of circuits and the operation of secondary valve-regulated lead-acid cells and
batteries in portable appliances. Requirements are specified which oblige the manufacturers
of appliances and secondary batteries to prevent the misuse of batteries in the course of
operation to provide protective measures avoiding injury to persons in case of battery failure
and to provide sufficient information to users.
This standard does not apply to secondary cells and batteries containing alkaline or other
non-acid electrolytes.

Exigences de sécurité pour les batteries d'accumulateurs et les installations de batteries - Partie 4: Batteries au plomb à soupapes pour appareils portables

L'IEC 62485-4:2015 s'applique aux aspects de sécurité liés à l'emplacement, à la disposition des circuits et au fonctionnement des éléments et batteries d'accumulateurs au plomb à soupapes dans les appareils portables. Des exigences sont spécifiées pour que les fabricants d'appareils et de batteries d'accumulateurs soient tenus d'empêcher l'utilisation impropre des batteries au cours de leur fonctionnement, de fournir des mesures de protection pour éviter de blesser les personnes en cas de défaillance de la batterie et de fournir des informations suffisantes aux utilisateurs. La présente norme ne s'applique pas aux éléments et aux batteries d'accumulateurs alcalins et autres accumulateurs à électrolytes non acide. Cette première édition annule et remplace la première édition de l'IEC TR 61056-3, parue en 1991. Cette édition constitue une révision technique. Cette édition inclut les modifications techniques majeures suivantes par rapport à l'IEC TR 61056-3:
a) mise à jour des exigences et une harmonisation du texte en cohérence avec la série IEC 62485.

Varnostne zahteve za sekundarne baterije in baterijske naprave - 4. del: Z ventili regulirane svinčeve baterije za prenosne aparate

Ta del standarda IEC 62485 se uporablja za varnostne vidike, povezane z prilagajanjem postavitve, razporeditvijo tokokrogov ter delovanjem sekundarnih z ventili reguliranih svinčenih celic in baterij za prenosne aparate. Določene so zahteve, ki proizvajalce aparatov in sekundarnih baterij zavezujejo k preprečevanju nepravilne uporabe baterij med njihovim delovanjem, zagotavljanju zaščitnih ukrepov, namenjenih preprečevanju telesnih poškodb v primeru okvare baterij, ter zagotavljanju zadostnih informacij uporabnikom.
Ta standard se ne uporablja za sekundarne celice in baterije, ki vsebujejo alkalne ali druge nekislinske elektrolite.

SAFETY REQUIREMENTS FOR SECONDARY BATTERIES
AND BATTERY INSTALLATIONS –

Part 4: Valve-regulated lead-acid batteries
for use in portable appliances

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 62485-4 has been prepared by IEC technical committee 21:
Secondary cells and batteries.
This first edition cancels and replaces the first edition of IEC TR 61056-3 published in 1991. It
constitutes a technical revision.
This edition includes the following significant technical changes with respect to the
IEC TR 61056-3:
a) updating of the requirements, and harmonisation of the text for consistency with the
IEC 62485 series.

INTRODUCTION
This standard provides information about the safety and health protection of persons when
using valve-regulated lead-acid batteries, which are used as a DC power supply systems in
portable appliances. Therefore the standard applies to commercially available valve-regulated
lead-acid batteries and battery systems.
IEC 62133 has preference for secondary cells and batteries containing alkaline or other non-
acid electrolytes.
In some portable appliances or toys the use of both primary and secondary cells or batteries
is possible. Where there is interchangeability of these cells or batteries, the standards for
primary batteries in the IEC 60086 series, Parts 1 to 5, have preference.
