IEC 60623:2017 pdf download.Secondary cells and batteries containing alkaline or other non-acid electrolytes – Vented nickel-cadmium prismatic rechargeable single cells
1 Scope
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.

3 Terms and definitions
For the purposes of this document, the terms and definitions given in IEC 60050-482 and the following apply. ISO and IEC maintain terminological databases for use in standardization at the following addresses: • IEC Electropedia: available at http://www.electropedia.org/ • ISO Online browsing platform: available at http://www.iso.org/obp 3.1 vented cell secondary cell having a cover provided with an opening through which products of electrolysis and evaporation are allowed to escape freely from the cell to the atmosphere Note 1 to entry: The opening may be fitted with a venting system. 3.2 nominal voltage suitable approximate value of the voltage used to designate or identify a cell or a battery Note 1 to entry: The nominal voltage of a vented nickel-cadmium rechargeable single cell is 1 ,2 V. Note 2 to entry: The nominal voltage of a battery of n series connected cells is equal to n times the nominal voltage of a single cell.[SOURCE: IEC 60050-482:2004, 482-03-31 , modified – Replacement of the words “a battery or an electrochemincal system” by” “or a battery” and addition of Notes 1 and 2 to entry.] 3.3 discharge voltage closed circuit voltage DEPRECATED: on load voltage <cell or battery> voltage between the terminals of a cell or battery when being discharged [SOURCE: IEC 60050-482:2004, 482-03-28] 3.4 rated capacity capacity value of a cell or battery determined under specified conditions and declared by the manufacturer Note 1 to entry: The rated capacity is the quantity of electricity C 5 Ah (ampere-hours) declared by the manufacturer which a single cell can deliver during a 5 h period when charging, storing and discharging under the conditions specified in 7.3.2. [SOURCE: IEC 60050-482:2004, 482-03-1 5, modified – Addition of the words “a cell or” in the definition, and of Note 1 to entry.] 3.5 CCCV charge method of charge consisting in a charge at Constant Current followed by a charge at Constant Voltage
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: –1 8 °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 1 85 P T-35/+45. Cells tested with CCCV charges shall carry the marking of CCCV: for example, KH 1 85 P CCCV. Cells tested at rapid charge shall carry the marking R and the value of the tested rapid charge current, expressed in multiple of I t A: for example, KH 1 85 P R1 . High grade cycling cells shall carry an additional marking C followed by the number of cycles: for example, KH 1 85 P C1 500. Cells having been tested with multiple types of tests shall carry the marking for the various tests performed: for example KH 1 85 P T-35/+45 CCCV R1 C1 500.
