Quartz Clock With No Battery
16 Answers
I have a Kelloggs Raisin Splitz quartz clock with alarm function. It's been in the loft for years. Obviously it's blank. I undid the back (held on by four of the smallest screws in the world!) to see what type of battery it had. There is no battery. It has two spring contacts to (presumably) two different metals on the back cover plate. It must work on the voltage between two different metals. I tried scratching the metals in the are of the contacts, but it still didn't work. Any ideas on how I might get it working? It's only a 'toy', but it would please me if I could get the display up again.

Douglas, there is no chance that the springs are to hold a battery. There is no room for a battery of any sort. The back cover as a metal disc of more or less white metal in the centre about 1cm in diameter, around that there is a thin plastic (insulating) ring and that is surrounded by a ring (an annulus) of yellow metal. One of the springs, which are tiny, touches the centre disc, the other touches the yellow ring.
SlackAlice, the whole item is no bigger than two AAA batteries.
Hans, the distance between the springs is about 1 mm. There is no receptacle for a battery to fit into. Also see first paragraph.
