The fully-discharged battery draws a high charging current from the power supply and overloads it, causing its output voltage to dip to the battery terminal voltage (close to 9 V) and rise as the battery charges. The sealed lead-acid battery, used for the demonstration, would already be as good as dead, with its terminal voltage far ...
The different contributions to the voltage drop in the lead–acid cell can be grouped in three main groups: those affecting the electrolyte resistance, those related to the material structure, electrodes and separators, and those involved in the electrochemical reactions at the double layer.
A lead acid battery is made up of a number of cells, each cell containing two electrodes (a positive and a negative plate) separated by an electrolyte. When the battery is being charged, electrons flow from the negative to the positive plate through the electrolyte.
The voltage across each cell during discharge will depend on a number of factors, including the type of electrolyte used, the size of the plates, and the rate at which discharge occurs. However, for a typical lead acid battery, the voltage will be around 2 volts per cell.
The actual voltage output of a lead acid battery will decrease as it nears empty. This is because as discharge progresses and more electrons are transferred from one plate to another, there is an increasing resistance to electron flow due to loss of active material on the electrode surfaces.
This phenomenon occurs when a lead-acid battery is left idle for an extended period of time and isn’t being used to power any electrical devices. When this happens, the chemical reaction inside the battery that produces electricity slows down and the overall voltage of the battery drops.
When a current is being drawn from the battery, the sudden drop is due to the internal resistance of the cell, the formation of more sulphate, and the abstracting of the acid from the electrolyte which fills the pores of the plate. The density of this acid is high just before the discharge is begun.

As the concentration of sulfuric acid decreases, the voltage of the battery drops. During the discharge process, the lead-acid battery generates a current that can be used to power an electrical device.

However, if the battery setup is only meant for emergency power and thus only expected to operate a few times a year, discharging a lead acid battery to 80% of capacity is not a big deal. There is no need to add extra battery capacity because the number of charge/discharge cycles is so low that there isn''t that much wear on the battery.
