What this standard covers, in our words

The North American safety standard for lithium CELLS. It covers primary and secondary lithium cells used as power sources in products, and evaluates them against abuse — short circuit, overcharge, crush, impact, heating — to reduce the risk of fire and explosion. Its subject is the cell and not the pack, and not the finished product the pack goes into: a pack assembled from UL 1642 cells is not itself certified to anything by that fact. Edition 6, 29 September 2020, last revised 12 October 2022.

This is our summary, not the standard’s own wording — the text itself is published by UL Solutions and it is the document to read before relying on anything here.

Each product below is listed against this standard alone, with the kind of evidence shown beside it — meeting or being certified to this standard does not imply compliance with any other.
