I generally have used a headlamp that uses three AAA batteries. I put fresh Alkaline batteries in each time I go out. It has never failed me.
What sort of batteries do you use in your headlamp? AA? AAA? CR123a?
Ni-Hydride? Lithium?

I might consider purchasing a rechargeable headlamp, but I have not researched cost yet, and what I have does work well enough.

Someone told me the Black Diamond Revolt 350 was a good one, and reasonably priced. It uses AAA rechargeable batteries, I think.
