9 Volt Battery

Today at the hardware store I was stocking batteries and it suddenly occured to me that I really like the look of the small rectangular 9 volt battery. Strange thing to pop into my head. Perhaps it is nostalgia. When I was a teenager I had a transistor radio that used a 9 volt rectangular battery. It was a strong sturdy-looking battery. One that that was worthy of keeping me in touch with the "top ten" hitmakers of the time, The Beatles and the Rolling Stones. Or maybe the attraction is the design with its clean lines and the simple black and copper of Duracell. And it won't roll off the table.
