Same as Copper Top
So I decided to sacrifice two Procells and two Duracell Copper Tops to see which lasted longer. All batteries were brand new and fresh from Amazon. Using two of the little Mini-Mag flashlights with the same type of bulb (from the same package) I found the following: The Copper Tops lasted 4 hours and 54 minutes. The Procells lasted 5 hours and 5 minutes, a difference of 11 minutes. They are exactly the same, as far as I am concerned. I'll be buying the Procells as they are the cheaper of the two.
