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] (7.3.8.1, 7.3.8.2); – insertion of IEC TR 62914 within the Bibliography.
