Notability Why is this type of battery considered notable enough to have an article Although the article title is nine volt battery it doesn t discuss any of the other types of nine volt battery and is thus wholly incomplete Similarly there appears to be no articles on one and half volt batteries three volt batteries or four and a half volt batteries etc etc I note that there is an article on lantern battery but I would argue that the same applies to that article There isn t very much of it any way 212 183 140 5
