Storage technologies vary, but some early DAB models, for example the first Pure Evokes from the autumn of 2002, store pre-set stations indefinitely without having any facility for fitting batteries. In any case the current required for such a role wouldn't justify D cells or anything like: a couple of AAs would be more than sufficient. I'm pretty sure the main intention of providing batteries was to allow a degree of free-roaming portability, it's just that the cost of replacing them would have put most folk off making much use of the provision.
