As a battery discharges, its voltage drops. This is because the chemical reaction that produces the electricity is not 100% efficient, so some of the energy is lost as heat.
When battery voltage decreases, the electrolyte acid within weakens, which reduces the acid flow rate to the plates and increases internal resistance. This strategy not only limits energy loss but also optimizes power delivery. Moreover, utilizing grounded or neutral conductors is highly beneficial, as they provide stability and safety
Battery capacity (measured in Ah) determines how much energy can be stored and delivered over time, impacting runtime. Voltage influences power output; higher voltage allows for more power delivery.

The charging current that flow into the battery depend of (charging voltage - battery open circuit voltage) / battery internal resistance. If the battery internal resistance increase or decrease, you need to increase or decrease charging voltage to maintain the same charge current. These is my reasoning
If by die, you mean depleted, then yeah pretty much the voltage decreases. If you mean a rechargeable battery getting worse over time, like in an old phone, it''s a little more complicated. It''s internal resistance increases, capacity (Amp-hours) decreases, and that voltage starts to drop faster with every discharge cycle.

As a battery discharges its stored energy, its voltage decreases. The rate at which the voltage decreases can be influenced by various factors, including temperature. For example, it may show that the battery''s voltage decreases as the temperature increases or that there is a specific temperature range where the voltage remains stable.

Internal Resistance: As a battery ages, its internal resistance increases, which can affect the voltage under load. This is one reason why older batteries tend to deliver lower voltages than newer ones. Part 3. Various types of voltage
After current decreases, battery voltage increases to about 2 V and changes slowly with time, which is the same to that in the second stage for battery with PTC. The temperature increase rate decreases owing to the decrease of PTC resistance. And then, the temperature at the middle of battery increases faster.

During Discharge: As a battery discharges, its voltage gradually decreases. For example, a lithium-ion battery will drop from around 4.2V (fully charged) down to 3.7V, then further to 3.0V (cut-off voltage), after which the device will stop working. During Charging: When charging, the battery voltage increases.
Generally, a battery's capacity is directly proportional to its voltage. As the voltage increases, the capacity also increases, allowing the battery to store more energy. This is why lithium-ion batteries with higher voltage typically offer longer usage times. 2. The Relationship Between Voltage and Discharge Curve
Voltage of battery increases and becomes stable slowly. These two stages are the same to other studies. At the third stage, the resistance of PTC increases after its temperature increase. The discharging current of battery decreases to the minimum. Joule heat in the “jelly roll” decreases to the minimum.
