Ha! That one's sold out. Go figure.

You know, I looked at one of the flashlight forums, and ... too deep for me. I just need a short course.

I looked for a C-8, per recommendation, but lots of variety. What does C-8 mean?

A have a handful of 18650 flashlights ... all of them have "-fire" in the name, somewhere. I guess I was going for the cheap stuff.

So do most of the batteries ... but those are better than the 18650 cells I got at the battery store here in town. Those are ... unpredictable. Seem to show they are charged but not really, then sometimes they do fine. These have the big bulge on top, some kind of protection. The "-fire" cells don't.
