Secondary cells and batteries containing alkaline or other non-acid electrolytes - Vented nickel-cadmium prismatic rechargeable single cells
IEC 60623 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 document, the former takes
precedence.

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 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 fifth edition cancels and replaces the fourth edition published in 2001 and constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition:
– optional characterization of cells designed for performances at very low and/or very high temperature; – optional characterization of cells tested with CCCV charge; – optional characterization of cells designed for rapid charge; – optional characterization of cells designed for high cycling.

NOTE 2 These currents are expressed as multiples of It A, where It A = C5 Ah/1 h (see IEC 61434). This group of two letters shall be followed by a group of figures indicative of the rated capacity of the cell in ampere-hours. Cells that have been tested at 20 °C and 5 °C but not at –18 °C shall carry an additional marking of T5: for example: KH 185 or KH 185 T5.
Cells in cases of plastic material shall be designated by the letter "P" after the figures: for example: KH 185 P. 5.2 Cell designation (optional) The additional marking shall be added to the mandatory marking. When the marking would exceed the available space on the cell, this information may be omitted on the cell but shall be provided in the documentation corresponding to the cell and in the type test report. If there is no mention concerning the marking for temperature, the cells shall have been tested at: –18 °C, 5 °C and 20 °C. Cells tested at other temperatures shall carry an additional marking of T followed by tested temperatures. In case the cell is characterized with both low and high temperature, they shall be indicated in increasing order with a solidus separating them: for example: KH 185 P T-35/+45.

7 Electrical tests 7.1 General Charge and discharge currents for the tests in accordance with 7.1 to 7.9 inclusive shall be based on the value of the rated capacity (C5 Ah). These currents are expressed as multiples of It A, where It A = C5 Ah/1 h.
7.2 Charging procedure for test purposes 7.2.1 General Prior to charging, the cells shall have been discharged at 20 °C ± 5 °C, at a constant current of 0,2 It A, down to a final voltage of 1,0 V.
Two charging methods are possible, to be selected by the cell manufacturers, in order to define their cells characteristics: – charge based on constant current; SIST EN 60623:2017
IEC 60623:2017 IEC 2017 – 11 –
– charge based on constant voltage, with a value of possible charging current (CCCV).
7.2.2 Charge procedure based on constant current Unless otherwise specified in this standard, the charge preceding the various discharge tests scheduled, shall be carried out in an ambient temperature of 20 °C ± 5 °C and at a constant current of 0,2 It A. The duration of the charge shall be 7 h to 8 h. 7.2.3 Charge procedure based on constant voltage at a given current This charge method is based on a constant current followed by constant voltage procedure (CCCV). The choice for the charge methodology for performance determination shall be defined before the start of the tests, and kept throughout all the testing procedures where indicated. For such charging methodology, two parameters are adjustable: current and voltage. They shall be clearly identified by the cell manufacturer in the description of the cell characteristics, as well as in the cell marking: for example KH 185 P CCCV R1. The charging methodology CCCV is described in Annex A. 7.2.4 Rapid charge current The charging current value for performance determination shall be selected before the start of the tests, and kept throughout all the tests where indicated. The design charge current value shall be indicated in the manufacturer’s documentation attached to the cell (e.g. 0,5 It A or 1 It A) which will be referred to as R in this standard, as well as in the approval documentation. This current is a maximum value. Table 4 shows preferred values for the rapid charge current: Table 4 – Maximum values for rapid charge current R Charge current for CCCV 0,5 It A 1,0 It A 2,0 It A 3,0 It A
In case no rapid charge current is defined, it shall be taken at 0,2 It A. Otherwise, the rapid charge current rate selected shall be clearly indicated in the report of test.
