That's not quite what 100% discharge usually refers. 100% discharge means from the maximum charge voltage to the minimum discharge voltage. That corresponds to, normally, using up the rated capacity of the cell.
On lithium batteries you'd normally only use 80% of the rated capacity if you want to maintain durability.

- jacquesm 5y agoExactly, depending on the make/model that's either 3.0V, 2.8V or 2.5V lowest discharge limit. If you go under that you basically can not longer trust the cell integrity and should dispose of it (no matter what miracle workers on the web say, the copper in the cell will have gone into solution and it can be deposited anywhere at all, but never again in the same spot where it was supposed to be so you are essentially the proud owner of an incendiary with a random length fuse...).
- elihu 5y agoAh, that makes sense. I guess it's kind of arbitrary (I mean, you could just call 80% full "100%" if that's all you'd use in practice) but it does seem quite useful if the "full" voltage is generally agreed to be in a narrow range and not have a wide range of maximum values depending on whether you care more about absolute capacity or longevity.
