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. The ...
