I bought some of these off ebay. They seem to work well. And hold a charge well too. I burned a light the other day for 6hrs and it was still going on the high setting. Anybody else have any thoughts on them?

I have been running this light on high for almost 3hrs now. 7 min shy as I type this. That's with this same Ultrafire protected battery. I'll turn it off at the 3hr mark for it is getting pretty dim. But they seem like good batteries in my opinion. I have some Trustfire flames. I'll have to see how they do. But I think these will give em a run.
