You mentioned it briefly, but when the cold weather camping season hits, I switch over to lithiums for the cold weather performance. I am not much into babying stuff, and trying to keep stuff warm all the time.

In headlamps and such in freezing temps, lithiums are the way to go.

All other times, I just go with alkalines.

I found it interesting that Petzl, one of the more popular headlamp manufactures, specifically states not to use lithiums in their headlamps due to overheating problems. Supposedly they can produce higher voltage than alkalines during their life cycle, even though they are all specified at the same voltage. Don't know for sure. I am also guessing that if you used them strictly in freezing temps, overheating may not be an issue? Not sure....

Engergizer on the other hand claims to replace any device damaged by their lithiums.....so go figure. I would still hate to be in the field and have a light fail, even if it could be replaced for free.

I just decided not to worry about it, and use Princeton Tec headlamps. They have no issue with the use of lithiums. Can you tell I like camping in the cold??? <img src="/ubbthreads/images/graemlins/laugh.gif" alt="" />
