CSA C22.2 NO. 62133-2:20

Preface This is the harmonized CSA Group and UL standard for Secondary Cells and Batteries Containing Alkaline or Other Non-Acid Electrolytes – Safety Requirements for Portable Sealed Secondary Cells, and for Batteries Made from Them, for Use in Portable Applications – Part 2: Lithium Systems. It is the first edition of CSA C22.2 No. 62133-2, and the first edition of UL 62133-2. This edition of CSA C22.2 No. 62133-2 replaces CAN/CSA-C22.2 No. 62133:17 (adopted IEC 62133:2012), Secondary cells and batteries containing alkaline or other non-acid electrolytes – Safety requirements for portable sealed secondary cells, and for batteries made from them, for use in portable applications. This edition of UL 62133-2 replaces the second edition UL 62133, Secondary Cells and Batteries Containing Alkaline or Other Non-Acid Electrolytes – Safety Requirements for Portable Sealed Secondary Cells, and for Batteries Made From Them, for Use in Portable Applications, published September 5, 2017. This harmonized standard is based on IEC Publication 62133-2: first edition, Secondary Cells and Batteries Containing Alkaline or Other Non-Acid Electrolytes – Safety Requirements for Portable Sealed Secondary Cells, and for Batteries Made from Them, for Use in Portable Applications – Part 2: Lithium Systems, issued February 2017. IEC 62133-2 is copyrighted by the IEC. This standard has been developed in compliance with Standards Council of Canada requirements for National Standards of Canada. It has been published as a National Standard of Canada by CSA Group. Scope This part of IEC 62133 specifies requirements and tests for the safe operation of portable sealed secondary lithium cells and batteries containing non-acid electrolyte, under intended use and reasonably foreseeable misuse. 1DV.1 D1 Modification to add the following paragraph and note to Clause 1: This standard is not, by itself, generally suitable for the evaluation of the safety of end-products, as it lacks specific requirements regarding charging, the effect of normal loads, abnormal conditions that should be considered, and the physical and electromagnetic stresses encountered in the anticipated environment of the end-product. NOTE Battery packs with additional features or circuitry, including integral circuitry that facilitates charging, are considered to be end-products. 1DV.2 DR Modification to add the following paragraph to Clause 1 (Canada only): This standard deals with the covered components used in accordance with CAN/CSAC22.2 No. 0.
