IEC 62133-2

What this standard covers, in our words

The international safety standard for sealed lithium cells and the batteries built from them, for use in PORTABLE applications. A cart's traction pack is not portable equipment, so a maker citing this for one has cited a standard written for a different application. It is a cell-and-pack standard and says nothing about the vehicle.

This is our summary, not the standard’s own wording — IEC (International Electrotechnical Commission) publish the text itself and it is the document to read before relying on anything here.

This standard is an independent claim about the products listed below — holding this certification does not imply compliance with any other standard.
