(Why Does) As a battery discharges, the voltage it produces decreases. However, the amount of voltage lost during discharge depends on the type of battery and how it is used. For example, lead-acid batteries typically lose about 2% of their voltage per cell per hour when discharged at a constant rate. As a battery discharges, its voltage drops.
As any battery ages, it will slowly lose its ability to hold a charge. This is due to a number of factors, including corrosion, electrolyte evaporation, and plate shedding. As the battery’s voltage drops, so does its capacity to power your devices. There are a few things you can do to prolong the life of your battery and prevent voltage drop.
Now remember, that a model for a battery is an ideal voltage source, internal resistance. when you start pulling current from the battery and complete the load there will be a voltage drop rI corresponding to the voltage drop due to the internal resistance this will cause the voltage of the cell to be lower than the voltage of the voltage source.
Applying a charge or discharge places the battery into the closed circuit voltage (CCV) condition. Charging raises the voltage and discharging lowers it, simulating a rubber band effect. The voltage behavior under a load and charge is governed by the current flow and the internal battery resistance.
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.
If you increase the load on a battery (decrease load resistance, add more light bulbs in parallel...) the current delivered by the battery will increase, causing an increased voltage drop across the battery's internal resistance and reducing the voltage measured between the battery terminals. This graph does not relate to the battery being used up.
