IEC 62133-2
IMPORTANT IN BRIEF
IEC 62133-2
IEC 62133-2 is an international standard that specifies safety requirements for portable, gas-tight secondary cells and battery packs made from them with alkaline or other non-acid electrolytes. It is one of the central safety specifications for rechargeable lithium-ion batteries and ensures a uniform standard in battery testing. Together with IEC 62133-1, it replaced the previous IEC 62133 in 2017.
Batteryuniversity is an independent and accredited testing laboratory specialising in battery testing and certification of lithium-ion batteries. We offer you all the tests required to obtain IEC 62133-2 certification: from mechanical stress tests and electrical test procedures to abuse tests to identify and minimise short circuits and other potential risks. We pay particular attention to ensuring that the tests for gas-tight secondary cells are carried out precisely and in accordance with standards. Our tests also take into account the specific properties of alkaline and acidic electrolytes.

Whether portable medical technology, button cells or high-performance industrial energy storage devices, we design our tests individually according to the requirements of your battery and fulfil the IEC 62133-2 standard. Our test methods are strictly based on the standard specifications.
The IEC 62133-2 safety standard and its significance for lithium-ion batteries
Lithium-ion batteries can be found in numerous end devices today, from portable electrical appliances to complex energy storage systems. Their high energy density makes them powerful, but also harbours risks such as short circuits, overcharging or thermal instability. IEC 62133-2 specifies safety requirements to ensure that batteries function reliably even under foreseeable loads.
Without a conformity test in accordance with this standard, approval problems or even safety-critical failures may occur. As a recognised testing laboratory, Batteryuniversity supports you in the certification process and ensures that your batteries are approved smoothly.
