[Author Prev] [Author Next] [Thread Prev] [Thread Next] [Author Index] [Topic Index] [Home] [Search]For years I have used the lithium cells in my Nikon F3's, and a friend uses them in FM2n's. These are all analog circuits contemporary to or predating the M6, and use SPD cells. In all cases the owner's booklets condone the use of the lithium cells and in all cases they have functioned flawlessly (as in fact they have in my 3 M6's).
