These batteries are, by some distance, the best non-rechargables I have used in a digital camera. The previous set lasted for well over 500 shots on a FinePix A80, including several months sat idle between uses. If you intend to use heavy-drain devices (digital camera, personal audio player, Xbox controller etc) on a frequent basis, you will probably get better value from a good set (at least 2500mAh) rechargeable batteries. If you are an occasional user, but require long lasting batteries when you do use your device, you can't go wrong with these, especially given some of the absolute bargain prices found on Amazon Marketplace.
