So it's been a bit brisk here in the Northeast of late. This weekend I took my RRT-0 with Li-Ion battery out for a walk. The flashlight was in my pocket. When I got home it wouldn't light at all. Checked the battery and there was plenty of voltage (~4.05V). After I held the light in my hand for a few minutes it came on full.
This morning I put a freshly charged *different* AW Li-Ion battery in the unit and placed it in my briefcase. The briefcase went in my car and I drove to work. The car warmed up to about 65 degrees during the 45 minute ride to work. It started out around 14. When I got to work the light was dead only re awoke after I held it for a few minutes.
So I know that Li Ion batteries aren't great for cold weather operation but this light seems to be specifically protecting them more than I would have thought. Since I can't believe the light has a temperature sensor in it I am wondering why it is so recalcitrant to light. I have never found Li-Ion chemistry to be *this* sensitive.
I need to know how this light is going to behave in the cold if I am going to trust it. Tonight I will put a Lithium primary in the light and leave it outside for an hour. If it won't work with lithium primaries then I just bought a 3-season flashlight
Anyone else have experience here?
