Thank you for linking the text. For anyone wondering, here is Ch. 2, Article 11 regarding portable battery replacement:

Article 11 Removability and replaceability of portable batteries

1. Portable batteries incorporated in appliances shall be readily removable and replaceable by the end-user or by independent operators during the lifetime of the appliance, if the batteries have a shorter lifetime than the appliance, or at the latest at the end of the lifetime of the appliance. A battery is readily replaceable where, after its removal from an appliance, it can be substituted by a similar battery, without affecting the functioning or the performance of that appliance.
2. The obligations set out in paragraph 1 shall not apply where (a) continuity of power supply is necessary and a permanent connection between the appliance and the portable battery is required for safety, performance, medical or data integrity reasons; or (b) the functioning of the battery is only possible when the battery is integrated into the structure of the appliance.
3. The Commission shall adopt guidance to facilitate harmonised application of the derogations set out in paragraph 2

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;

(b) professional medical imaging and radiotherapy devices, as defined in Article 2, point (1), of Regulation (EU) 2017/745, and in-vitro diagnostic medical devices, as defined in Article 2, point (2), of Regulation (EU) 2017/746.
