Flashlight

I was digging around in my old work tool box of when I retired in 2004. I ran across a old work flashlight which I thought was junk. To my surprise it still worked after sitting for over 11 years with the same old D cell battery's in it. So I tested the battery's and they still had over 1.3 volts in them and they were still clean. It must be the different between cheap dollar store battery's and top brand battery's.
