Hi Brian, UN 38.3 applies to batteries shipped in products, shipped with products, and shipped alone. In other words, all batteries. There aren't size exceptions that I am aware of with the exception of button/coin cells shipped installed in equipment. IATA has a good summary of air shipping requirements. lithium-battery-guidance-document.pdf (iata.org)<https://www.iata.org/contentassets/05e6d8742b0047259bf3a700bc9d42b9/lithium-battery-guidance-document.pdf>

Learn why this is important<https://aka.ms/LearnAboutSenderIdentification> Hello fellow compliance colleagues, Holy smokes but UL 38.3 is poorly written. Can someone confirm that the scope only applies to batteries sold and shipped separately, and do not apply to those installed in an appliance-product? Secondly, I can't find a size limit in the scope. For instance, I can't believe it applies to lozenge batteries, but I cannot confirm that either. Lastly, has anyone on this list heard of a "cold start battery" in the context of an residential or industrial appliance? I'm familiar with automotive batteries that have cold-start or cranking ratings, and of utility-scale "grid" battery plants that can be black start qualified. This is clearly different, yet I can't find bupkiss on it apart from mention by a buzzword-bombast who likes to throw fancy terms around, and now I'm stuck trying to justify or qualify the two 3V, 5 A-hr cells in our latest charger against this "cold start" metric. thanks all, Colorado Brian ________________________________ This message is from the IEEE Product Safety Engineering Society emc-pstc discussion list.
