IEC 62133-2:20 7+A1:2021规定了便携式密封二次锂电池和含有非酸性电解质的电池组在预期使用和合理可预见的误用下安全操作的要求和测试。 该第一版取消并取代了2012年发布的IEC 62133第二版。它构成技术修订。 本版本包括以下与IEC 62133:2012相关的重大技术变更: -将镍系统分离成单独的部分1； -包括纽扣电池要求； -更新将电池组装成电池(5.6)； -机械试验[振动、冲击](7.3.8.1、7.3.8.2)； -在参考书目中插入IEC TR 62914。

IEC 62133-2:2017+A1:2021 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.
This first edition cancels and replaces the second edition of IEC 62133 published in 2012. It constitutes a technical revision.
This edition includes the following significant technical changes with respect to IEC 62133:2012:
- separation of nickel systems into a separate Part 1;
- inclusion of coin cell requirements;
- update of assembly of cells into batteries (5.6);
- mechanical tests [vibration, shock] (7.3.8.1, 7.3.8.2);
- insertion of IEC TR 62914 within the Bibliography.
