Yes, it does get lower. The effect you see is called internal resistance: A practical electrical power source which is a linear electric circuit may <...> be represented as an ideal voltage source in series with an impedance. This impedance is termed the internal resistance of the source. Put simply, a battery is not an ideal voltage source.
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.
This is why shorting a battery momentarily returns to some charged voltage level by the exchange of charge Q=CV between multiple layers of dielectric charge. Current is simply the rate of change of charges per second.
When the battery is open you are measuring an open cell voltage. When the battery is in the system it's closed cell voltage under load. You are dropping some voltage across the internal impedance of the battery because your system is drawing current when the measurement is being made (so at the terminals the voltage is indeed lower).
unfortunately it says nothing about ESR of batteries which is why Voltage decreases with rising current. In general, the answer to your your question is, "yes". As other answers have pointed out, a battery has an effective resistance. This is, in part, do to the fact that the internal structure has an intrinsic resistance.
Since the diffusion and migration of lithium ions slow down at low temperatures and the electrolyte viscosity increases, the temperature rise of a lithium-ion battery is larger at low temperatures than at high temperatures. This is because the battery’s internal resistance rises as a result.

When current flows from a battery, does voltage decrease?
Once current begins to flow, electrons are now moving through the circuit. Does this mean that the voltage actually begins to decrease as a direct result of current flow? Specifically are electrons "used up" or do they simply lose energy (dissipated as heat in circuit) which leads to a lower voltage potential? Or another scenario, do the ...
