Whether a battery is a constant voltage source or current source

Thus, when you draw current from the battery, the voltage across the resistor goes up which means the voltage across your circuit goes down. Eventually you deplete the battery. When this happens, we can no longer treat all of the parts of the battery in bulk. Parts of the battery will remain charged, other parts will be fully discharged.
