These cells are hilariously fake. I had to replace my headworn Cree LED lamp thing. The older I get the more light I need, as I was about to embark on modding nine minature transceivers I needed max light as the internals are smallest size SMD and just about microscopic.
Anyway, I found a quick dispatch Cree LED fitted headset with a free set of two 18650 button tops. I didn't need the cells but what the hell.
Headset is fine, real Cree LEDs, but the 18650s are very, very fake and a good example of what is out there. They are button top, but there are plenty of flat top fakes around too, don't be lulled into a false sense of security!
1. They have the same colouring as "UltraFire" cells, often sold for lamp use, they are very often fakes, in fact I think genuine ones are garbage too. But note the name on the cell -
UitraFlrc
2. See photo:Text on the side - LX 18650 6800mAh 4.2V. Miracle 6800mAh! Tesla cars will be pleased
I bravely fitted them into the headset, there's no way I'm going to use 2 x these things strapped to my head btw, there was a glow but not much. Nor will I charge them in the headset....
I put them into a MiBoxer charger, see photo, at start = 2% charge, 3.46V, 189 - 192 megohm each, started at 0.20A charge rate. It took 30 mins at that very low rate to come to 100%, another miracle!
They weigh 27g each, way too light for 18650 that should be no less than around 42g. So they have a much smaller cell inside and packing material, the standard ripoff technique.
Disgusting, dangerous and nasty. I'll keep one and when it's discharged and I have time I'll cut it open, outside. Yes I have done it before - don't do it yourself btw!
Photos - a bit of a rush so only two sorry.
