FOREWORD

1) The IEC (International Electrotechnical Commission) is a worldwide organization for standardization comprising

all national electrotechnical committees (IEC National Committees). The object of the 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, the IEC publishes International Standards. 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. The 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 the 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 National Committees.

3) The documents produced have the form of recommendations for international use and are published in the form

of standards, technical specifications, technical reports or guides and they are accepted by the National

Committees in that sense.

4) In order to promote international unification, IEC National Committees undertake to apply IEC International

Standards transparently to the maximum extent possible in their national and regional standards. Any

divergence between the IEC Standard and the corresponding national or regional standard shall be clearly

indicated in the latter.

5) The IEC provides no marking procedure to indicate its approval and cannot be rendered responsible for any

equipment declared to be in conformity with one of its standards.

6) Attention is drawn to the possibility that some of the elements of this International Standard may be the subject

of patent rights. The IEC shall not be held responsible for identifying any or all such patent rights.

International Standard IEC 60623 has been prepared by subcommittee 21A: Secondary cells

and batteries containing alkaline or other non-acid electrolytes, of IEC technical committee 21:

Secondary cells and batteries.

This fourth edition cancels and replaces the third edition published in 1990, Amendment 1

(1992) and Amendment 2 (1992), and constitutes a technical revision.
The text of this standard is based on the following documents:
FDIS Report on voting
21A/327/FDIS 21A/329/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 3.

The committee has decided that the contents of this publication will remain unchanged until

2006-01. At this date, the publication will be
 reconfirmed;
 withdrawn;
 replaced by a revised edition, or
 amended.

INTRODUCTION

Traditionally the manufacturers and users of alkaline secondary cells and batteries have

expressed the current used to charge and discharge these cells and batteries as a multiple of

the capacity. For example, a current of 20 A used to charge a cell with a rated capacity (C Ah)

of 100 Ah would be expressed as C/5 A or 0,2 C A. This method of current designation has

been used in earlier standards relating to alkaline secondary cells and batteries.

Comments have been made, however, that this method of current designation is dimensionally

incorrect, in that a multiple of the capacity (ampere-hours) will be in ampere-hours and not, as

required for current, in amperes. As a result of these comments, the method described in

IEC 61434 has been used in this standard.

In brief, the method states that the reference test current (I ) is expressed as:

C Ah
I A =
1 h
where
C is the rated capacity declared by the manufacturer in ampere-hours (Ah), and
n is the time base in hours (h) for which the rated capacity is declared.

1 General
1.1 Scope

This International Standard specifies marking, designation, dimensions, tests and requirements

for vented nickel-cadmium prismatic secondary single cells.

NOTE In this context, "prismatic" refers to cells having rectangular sides and base.

When there exists an IEC standard specifying test conditions and requirements for cells used

in special applications and which is in conflict with this standard, the former shall take

precedence.
1.2 Normative references

The following normative documents contain provisions which, through reference in this text,

constitute provisions of this International Standard. For dated references, subsequent

amendments to, or revisions of, any of these publications do not apply. However, parties to

agreements based on this International Standard are encouraged to investigate the possibility

of applying the most recent editions of the normative documents indicated below. For undated

references, the latest edition of the normative document referred to applies. Members of IEC

and ISO maintain regist
