Being Kodiak brands I thought they were good quality and would last more than one night. I have used them in flameless candles and in a string of lights that have timers for 4-6 hours of operation and turn off automatically. The next evening they glowed and the light was almost invisible because the batteries were dead. Put in fresh ones from the same pack and they did it again the next night. I have tried some of my Revain brands and they have lasted over 2 weeks. Not my headlights, their batteries aren't worth crouching down. Glad I didn't use them on any of my medical equipment!
