Leica rangefinder dead from no use?

[upjeeper]

I’ve got a Leica rangefinder I bought almost 20 years ago and it’s sat in my safe since. It doesn’t want to seem to power up with new batteries, any thoughts?

Are the contacts corroded? Try using a pencil on the contacts and then the eraser these should help if not I am as much at a loss as you are.
