The Dollar Tree Stores have an assortment of batteries, most of them are not name brand batteries but they work just as well. I can purchase a pack of 4 AA batteries for a dollar here and get as much use out of them as the name brand ones from other stores that charge much more for them.
The no name batteries are just as powerful as the brand names! Quality is not all in the name; it is in the game!!! If performance is what you are looking for then buy the Dollar Tree Store's batteries and see for yourself that more money doesn't mean more usage!
