According to the document, a device’s portable battery can be considered “readily removable and replaceable” when it can be removed “with the use of commercially available tools” or specialised tools that are packaged with the product at no extra cost.
So yeah, if the battery was not glued it would be in regulation, but it’s one of the things most teardowns complain, the battery is almost super glued in.
