IEC 62133:2012 PDF Download

IEC 62133:2012 is a safety standard that sets out the requirements and tests for the use of portable sealed secondary cells and batteries containing alkaline or other non-acid electrolytes in portable applications. The standard covers the safe operation of these cells and batteries under intended use and foreseeable misuse scenarios.

The 2012 edition of the standard includes several significant technical changes compared to previous editions. These changes include updates to the assembly of cells into batteries and the addition of design recommendations specifically for lithium systems. Additionally, the standard now separates nickel systems and lithium systems into separate clauses, each with their own set of requirements and tests.

One notable addition to the standard is the inclusion of specific requirements and tests for lithium systems. This reflects the increasing use of lithium-ion batteries in portable applications and highlights the importance of addressing the unique safety considerations associated with these systems.

Furthermore, the standard includes an annex on the safe charging of secondary lithium-ion cells, providing guidance on how to safely charge these cells for use in portable applications.

It's worth noting that the corrigendum issued in June 2013, which addresses any errors or omissions in the standard, has been included in this edition.
