>some products, such as medical devices and so-called “wet appliances” (for example, electric toothbrushes or water flossers), are already exempt from this requirement, mainly for safety reasons. In these cases, batteries only need to be removable and replaceable by independent professionals.

Note: this is exemption from user replacing battery themselves, not a blanket exemption on the product not being serviceable for battery

As people will be wearing wearable products when it is raining these categories of clothes products have been classified as wet products
