Standards & Compliance
The ETENWOLF Air3 battery pack has been tested against the following internationally recognised safety standards for portable sealed secondary lithium cells and batteries:
- IEC 62133-2:2017 – Safety requirements for portable sealed secondary lithium cells and batteries containing alkaline or other non-acid electrolytes, Part 2: Lithium systems.
- IEC 62133-2:2017/AMD1:2021 – Amendment 1 to IEC 62133-2:2017, incorporating updated safety test requirements for lithium battery systems.
- EN 62133-2:2017/A1:2021 – European harmonised adoption of the above IEC standard, applicable for the European market including the KR and GB national differences evaluated.
Compliance with IEC 62133-2 covers a comprehensive set of safety tests including overcharge, overdischarge, external short circuit, crush, drop, thermal abuse, and vibration, among others. These tests verify that the battery pack will not pose fire, explosion, or leakage hazards under normal and foreseeable misuse conditions.
