In between the fully discharged and charged states, a lead acid battery will experience a gradual reduction in the voltage. Voltage level is commonly used to indicate a battery's state of charge. The dependence of the battery on the battery state of charge is shown in the figure below.
The actual process is dependent on the type of battery we are talking about. In a lead acid battery, The cell voltage will rise somewhat every time the discharge is stopped. This is due to the diffusion of the acid from the main body of electrolyte into the plates, resulting in an increased concentration in the plates.
Gassing introduces several problems into a lead acid battery. Not only does the gassing of the battery raise safety concerns, due to the explosive nature of the hydrogen produced, but gassing also reduces the water in the battery, which must be manually replaced, introducing a maintenance component into the system.
The batteries were chosen to be kept at open circuit voltage for 800 min because some works have shown that for lead acid batteries, the state of charge can be derived at open circuit voltage when the battery is disconnected from the load for at least two hours and this OCV is linearly proportional to the Depth of Discharge (DOD) .
It was demonstrated that the magnitudes of open circuit voltage and energy recovery of lead acid battery have relationships with the health status of the battery which if well exploited, can lead to innovations in the science of state of health determination for lead acid batteries.
Test show that a heathy lead acid battery can be charged at up to 1.5C as long as the current is moderated towards a full charge when the battery reaches about 2.3V/cell (14.0V with 6 cells). Charge acceptance is highest when SoC is low and diminishes as the battery fills.

Explained: What Causes Battery Self-Discharge
Some batteries have a low self-discharge rate and hold onto their energy tightly. On the other hand, older lead acid batteries may lose their charge a lot quicker with a higher self-discharge rate. Factors such as temperature, battery pack assembly, and even the state of charge can influence the rate of energy loss.

Batteries naturally lose power when left sitting idle. This is called self-discharge. The self-discharge rate for a lead-acid battery is about 4% per month. This number may be compounded by parasitic draw from the electronics in your vehicle. The longer your battery sits, the more it will discharge, leaving it open to sulfation and stratification.
