For LiIon it depends on actual LiIon chemistry, here is two examples:
/Keeppower%2018650%202600mAh%20(Black)-Capacity.png)
/Keeppower%2018650%203400mAh%20(Black)-Capacity.png)
One is about empty at 3.1 volt and the other has lot of capacity left.
You can try comparing some more batteries in my comparator.
