As the chemistry shifts with discharge (or charge) the no load voltage changes slightly and the internal resistance changes as well. A battery is considered to be a voltage source because the galvanic activity they use to store and deliver energy has a fixed voltage across it. However, a battery is not an ideal voltage source.
A battery, which is a DC power source, can be used to convert DC current into AC current, making it a valuable source of AC power. This innovation has paved the way for portable AC power supplies, enabling us to use AC-powered devices even in remote locations.
However, a battery is not an ideal voltage source. All real sources have some built in resistance. In the case of a battery, the effect is well modeled as an ideal voltage source in series with a small resistor (I don't know numbers, but I'd expect it to be single digit ohms).
Currently, most of the technology we use operates on either AC (alternating current) or DC (direct current) power. AC current is what we typically find in the power supply to our homes, while DC current is what batteries produce. Traditionally, batteries have been used as a source of DC power, making them suitable for a wide range of applications.
While a battery operates as a source of DC, meaning it provides a direct flow of current in one direction, the power supply can either be a battery or a source that operates on AC, meaning the current alternates its direction periodically. AC current is the type of current that is commonly used in homes and businesses.
A battery is a common source of DC power. It contains one or more cells, where each cell produces a fixed voltage. When multiple cells are connected together in a battery, their voltages add up to create a higher total voltage. This DC voltage can be used to power various electronic devices.

What is a Circuit?
Voltage Source - this provides the electrons that flow through the circuit in order to power it. Common voltage sources are batteries and electrical connections such as outlets. Load - this consumes the power created by the voltage source. Loads are what make a circuit light up, make noise, run a program and more. In simple circuits, the load ...

Would a battery be considered an independent or dependent voltage source?
In the physics world, batteries are often used to represent a voltage source. I feel like that a battery should be considered a dependent voltage source since a batteries voltage is dependent on the amount of current the load draws within a certain amount of time. An ideal battery wouldn''t have this issue. But to me, batteries aren''t ...
