While the battery aims to deliver a constant voltage, the current can vary depending on the resistance of the circuit to which it is connected (Ohm''s law). Therefore, a battery does indeed provide a source of constant voltage, and it is the circuit that determines the current that flows as a result of this voltage.
In a battery, the number of protons and electrons in the system are fixed, causing a constant voltage that varies with the charge of the battery.As the electrons flow from one terminal to the other, the voltage drops because there are less free protons.
A battery is a time-varying constant voltage source. In order to understand this a little bit better, you have to understand why an AC-DC power supply is not constant voltage. The source of the electrons across an AC-DC converter comes from free electrons on a conductor.
in the Norton model the battery is a constant current source in parallel with the internal resistance. if the internal resistance is very low compared to the load, the battery is connected to, looking at it as a Thevenin model (a voltage source) makes more sense.
When a battery is connected to a circuit, the electrons from the anode travel through the circuit toward the cathode in a direct circuit. The voltage of a battery is synonymous with its electromotive force, or emf. This force is responsible for the flow of charge through the circuit, known as the electric current.
As you can see the power supply will try to provide a constant current by reducing the output voltage. Characteristics of Constant Current Source: Fixed Output Current: The current supplied by a CC source remains constant. Varying Voltage: The voltage adjusts based on the resistance or impedance of the load.
If you're trying to output more current than your battery can source, than the voltage across the load goes down. V=IR; in the beginning of the discharge (cycle) there is more current coming out of the battery, which shows up as a higher voltage, and in the end, there is less, which translates into a lower voltage.
While the battery aims to deliver a constant voltage, the current can vary depending on the resistance of the circuit to which it is connected (Ohm''s law). Therefore, a battery does indeed provide a source of constant voltage, and it is the circuit that determines the current that flows as a result of this voltage.

What defines a voltage source is that the voltage does not change when the load changes (i.e., when the current changes). Within some limited range of current, a battery can be a pretty good approximation of a true voltage source in series with a small …
The larger the external current, the greater the required rate of chemical reactions and thus, the lower the voltage across the terminals. As long as the circuit current is significantly less than the maximum current the chemicals reactions can sustain, the voltage across the battery terminals will be close to the open circuit voltage.

Batteries are constant voltage providers, not constant current providers.The current a battery supplies depends on what it''s connected to. If it''s connected to a low resistance, then it provides a big current, and shifts energy quickly.If it''s connected to a high resistance, then it provides a small current, and shifts energy slowly.
