The other article you just provided clears the matter, the one referenced in the thread seemed to attribute the "exemption" to the "battery regulation" one.
But the "battery regulation" is already approved, while the "Ecodesign" is still only a draft (from what I can understand).
It will be interesting to see how the EU will solve the "overlapping", it seems to me improbable that they will make in September (after the hypothetical approval of the "ecodesign" draft) an amendment to something approved only a few months before.
