Amund If the battery manufacturer knows what they are doing you may well find that the battery has been “designed to comply” with IEC 62133-2 but that particular variant has not been subjected to certification testing as they were waiting on a minimum order, or a customer who needed it.
A competent battery manufacturer should be able to arrange this for you as a matter of routine for a fee.

The battery isn’t usually operational during this phase of its life. So although some tests are similar, UN38.3 cannot be considered an alternative to IEC 62133-2.

Seems we might have an issue here since the cells are not IEC62133-2 approved. But the cells are UN38.3 certified. And we are now running UN38.3 on the complete product (product and cells includes). Do you know if such UN38.3 tests will be good as IEC62133-2 compliance?

You only get to comply with Annex M if you pass M.2.1 which requires that cells comply with the relevant IEC standard. IEC 62133 (all parts) are in Annex ZA as an undated reference meaning you should be looking to use the latest one - this is currently IEC 62133-2:2017+A1:2021. Many (reputable) battery manufacturers will be aware of this and will have battery packs that are pre-certified to the latest standard.

It contains Lithium LiPo batter. According to EN/IEC62368-1-1:2020, § M.2 Safety of batteries and their cells, the standard IEC 62133-2 is listed, and batteries and cells shall comply according to that standard. Could this be interpreted as an invariable requirement, that if you are to fulfill EN62368-1 and have LiPo cells in your product, then the cells must comply with this standard IEC 62133-2? How well known is IEC 62133-2? Thanks!
