duracell is ultraJuly 28, 2008 I use these batteries to read long in to the night. They work, but I feel guilty throwing them out even if I recycle. Sometimes the packages are hard to open, but don't worry, I can cope. I am not sure what else you can say about batteries...in fact I NEVER think about batteries until I run out and need them. So that is why I use the endless shopping deal. I really never run out of batteries right in the middle of the best part of the book!!
