I had about a dozen identical UltraFires (the most common no-name cheapo) and peeled the labeling off of them to find every one was a different recycled used piece of crap (see photo of Chinese factory below). A good 18650 3400mAh battery costs at least $20 each. Everything we have used daily for the last several years is Nitecore brand.

Nitecores are good. I only use Panasonics now on everything. If there's a something Fire at the end, I stay away form. From Sunfire to Ultrafire or whatever. They are all junk, including the flashlights and drop-ins.
