Not a real 18500
"The Olite 18500 185C2 is not usable in normal 18500 applications such as Solar LED lights because of a black plastic ring around the positive tab that prevents the + tab from touching the + tab of the appliance. I used a file to remove some of the battery's black plastic protective ring and it now works normally. I would recommend the Panasonic 18500 2040 mAh battery instead."
