The ratio you get per dollar with these batteries is much higher than any other battery available. They don't last the longest, but if you can live with replacing them a little more often, you'll get a lot more bang for your buck. ). They have an average voltage of 1.58-1.6V. The battery life I received was almost 5 years from the date of purchase. After 6 months of storage, the few remaining show a voltage drop of less than 0.02V. I tested them in a small black diamond headlamp to compare with other batteries. They lasted about 80 hours. Duracell ultra lasted about 90 hours. Revains lasted about 75 hours. The port transport took about 75 hours. The Energizer battery lasted about 40 hours (any rechargeable battery would give the same result). So as you can see they don't really last as long as others (I know for a fact that I tested Duracell, I'm sure there are others), but when they're not critical they last the longest (e.g .in a headband flashlight where you don't want to carry spare batteries) then this is a great economical battery. If you're using them for a camera flash or something else that drains a lot of power quickly, you might want to look into lithium batteries - they'll do a better job for your purpose. this (even if you only receive one delivery).
