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 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.
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).
In practice this is not the case as: The terminal voltage of a battery decreases, as the current it supplies to a circuit increases. This is the same for all real voltage sources. (However power supply designers do produce stabilised power supplies, where feedback circuits are used to maintain a relatively constant output voltage).
Batteries are an integral part of our daily lives, powering everything from smartphones to cars. At the heart of a battery’s ability to provide power is its voltage. Understanding battery voltage is not just a matter of technical knowledge; it’s essential for ensuring device compatibility, safety, and optimal performance.
Battery voltage is the electric potential difference in a battery. Critical for ensuring device compatibility and safety. Tools like multimeters are used; understanding readings is crucial. Includes temperature, battery age, and usage patterns. Proper handling is essential to avoid risks. Optimal charging practices and usage extend battery life.
