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 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.
The voltage of a battery is a fundamental characteristic of a battery, which is determined by the chemical reactions in the battery, the concentrations of the battery components, and the polarization of the battery. The voltage calculated from equilibrium conditions is typically known as the nominal battery voltage.
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.
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.
Neither. It's one or more electrochemical cells. Under no load it has a 'constant' potential. When loaded the chemistry presents as internal resistance and the voltage will drop. As the chemistry shifts with discharge (or charge) the no load voltage changes slightly and the internal resistance changes as well.

Get PriceA battery differs from a true constant voltage source in several ways. First, a battery provides a voltage that changes as its charge depletes. As the battery discharges, the voltage gradually decreases. In contrast, a true constant voltage source maintains a fixed voltage regardless of the load or the current drawn from it.
