IEC62133 test report

What is IEC62133 for lithium battery then?

It’s a worldwide safety requirements and tests for batteries. The first version is IEC62133-2012 version, it was released by the International Electrotechnical Commission(IEC) in 2012,They replaced the 2012 version with IEC62133 2:2017 verion in 2017.The official definition by IEC website is as below:

IEC 62133-2:2017 

Secondary cells and batteries containing alkaline or other non-acid electrolytes – Safety requirements for portable sealed secondary lithium cells, and for batteries made from them, for use in portable applications – Part 2: Lithium systems


IEC 62133-2:2017 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] (,;
– insertion of IEC TR 62914 within the Bibliography.
