A couple of suggestions. Try going to a battery site and cross referance or go to one of the russian sites that sells russian scopes and ask them. I do beleive I have the same scope you are talking about.

I havnt used it in years because I have a 3rd generation U.S. make that I like better. But any way the scope came with a Tiger SVD and I asked the same question about the batteries if they died since the batteries looked different. I wish I could remember the answer, but it was, there is a battery, that will work, just cant rememer what one
Sorry.
