Hello, A few days ago my father handed me his old Minox 35 GT without telling me anything about it. He said he couldn't remember much, so I read the manual. And now I have discovered that my battery is out (which isn't surprising after all these years). I first thought it would be a piece of cake to get a new battery, but turns out that all the battery types that the old Minox manual suggests are illegal because of the mercury. Since I know little about batteries, can someone please suggest something? What should I buy? I've been looking around on the internett and see a lot of different combinations people do - some buy two smaller batteries and use them, while others buy four even smaller. The things is, though, I am such a novice when it comes to batteries that I don't think I could manage making my own combination. There are so many different types! Could someone tell me an easy way of sorting this out? What kind of batteries I need? I am so eager to try the damn thing! Thanks!
