Summary: Duracell batteries DO have energy!
Comment: Its true these battery do have energy inside them, its another marvel of modern science. Personally I noticed that the flow of electrons were very strong, a nice change after years of dealing with batteries that only had strong to moderately strong electron flow. You mainly notice this when you bridge the terminals with your mouth (dont try this at home, well, actually if you do try it, it will probably be at home. But dont try it at WORK you will look like an idiot)
I did notice however that the longer I left the battery bridged in my mouth the less painfull it became, this was over a period of like 3 days straight though which was promising. At first I didn't know if it was just my nerve endings getting fried off or if this behemoth of a battery was actually losing power. But after a couple more days I started to regain feeling in my lower lip and I knew the ride was almost over and the battery was indeed growing weeker. Overall this was the longest lasting battery I have personally experienced. I would recommend it to anyone with a taste for adventure!

Summary: Powerfully Entertaining...addictive
Comment: I've used many batteries by various manufacturers but these were a real treat. From the start they were full of energy -- so powerful that the volume dial had to be kept to a minimum. Though their intensity lessened as the hours passed, by the the time they were expended, I couldn't help myself from buying more.Tip:
If you are willing to purchase several cassette players and enough of these batteries, you can exeperience many books on tape simultaneously. This saves time while exposing you to more literature that your friends would be able to digest if they devoted all of their waking hours to reading.
