Can a battery go down to zero volts?
It is safely impossible to drop an ideal battery to zero volts. A battery cannot go down to zero volts because of the internal chemistry. In a standard use, you cannot drop the voltage below 2 volts, even if you wired the terminals together. Batteries will vary between 3.8 and 2.4 volts per cell. As voltage drops, internal resistance rises.
What if there is no current flowing out of a battery?
If there is no current flowing out of the battery, ohm law says that there is no voltage drop in R1. Thus the output voltage of the battery is V0: the nominal voltage of your battery. You are talking about a "singularity" here ...
Can You recover a lithium ion battery from zero volts?
Recovering a Lithium-Ion battery cell from zero volts is not recommended, as it can result in a fire. This is because once the cell goes under about 2.5 or 2.6 volts, a chemical reaction occurs inside the cell that permanently damages it and drastically increases its internal resistance.
How do you know if a battery is safe?
A safe battery is a dead battery and a dead battery and a dead battery is approximately 2 volts. If you have dropped the voltage to zero, I can tell you that you have done more than neutralize the cells, you have fundamentally altered the structure of the battery. Li-Ions are sensitive and finicky.
Why can't I drop a Li-ion battery to zero volts?
Check the Why Can't I drop it to zero volts header. Almost every Li-ion battery has copper as anode current collector. When copper is exposed to high anode voltage due to high discharge, the copper dissolute in to the electrolyte provoking internal electrical resistance rise.
What does V=IR mean if a battery has zero voltage?
According to Ohm's law V=IR. This means that if the current is zero there is no voltage. Does this mean also that an unplugged battery has zero voltage? Then why does it say otherwise in the package. What does it mean that a battery is 1.5 Volts if, after all, it depends on the resistance?

Batteries and their connections to loads are not zero resistance devices, they have an internal resistance so there will be a voltage drop across them, and that voltage drop increases as the load (current) increases. The greater this (non-load) internal resistance the more the battery connection voltage will drop with as load increases.
