Okay, so back in summer 2009 or 2010, I bought an atomic clock from a Radioshack in Nitro, West Virginia (I was visiting my grandparents at the time), and then put some standard Duracell batteries in it. Since then I have NEVER had to change the batteries. The package said it would run for about a year....it's been about 3 years and that thing is still running. It's been through 6 houses, 4 states, been through flight after flight, and still works like a charm. I have never been able to explain why... What do you guys think, does my clock have a Uranium battery inside of it? Did I just get lucky with the Duracells? inb4aliens
