A cheap battery with a ridiculous rating from ebay, that can only give one result.

The best battery can deliver about 1.6Ah at lower currents, the other do not really work.

Not enough energy to really warm the cell.

Conclusion
No surprise this is a bad battery. My guess is that it is a used cell with a new top, bottom and wrapper.

Nothing new, tanks for reviewing it.
It seems more as a cell “already recharged 1800 times”… Evil

Thanks for the review! I’m amazed they couldn’t even source a decent Chinese 2,200mAh cell, and those can be found everywhere for about a dollar each.

Recycled cells maybe? There are tons of unsold powerbanks manufactured in the last couple years and maybe they are just re-wrapping the cells.

I’m going to get me some of these to use in the world’s brightest flashlight, the ShadowHawk X800!
