"2. By way of derogation from paragraph 1, the following products incorporating portable batteries may be designed in such a way as to *make the battery removable and replaceable only by independent professionals*:

(a) appliances specifically designed to operate primarily in an environment that is regularly subject to splashing water, water streams or water immersion, and that are intended to be washable or rinseable;"

This still does NOT allow non-replaceable batteries. Also note "independent".
