In the charging process we have to pass a charging current through the cell in the opposite direction to that of the discharging current. The electrical energy is stored in the form of chemical form, when the charging current is passed. lead acid battery cells are capable of producing a large amount of energy.
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.
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 battery may also fail as an open circuit (that is, there may be a gradual increase in the internal series resistance), and any batteries connected in series with this battery will also be affected. Freezing the battery, depending on the type of lead acid battery used, may also cause irreversible failure of the battery.
Construction, Working, Connection Diagram, Charging & Chemical Reaction Figure 1: Lead Acid Battery. The battery cells in which the chemical action taking place is reversible are known as the lead acid battery cells. So it is possible to recharge a lead acid battery cell if it is in the discharged state.
Nevertheless, it should be clearly understood that wet (filled) lead acid battery is “a live” product. Whether it is in storage or in service, it has a finite life. All batteries once filled will slowly self discharge. The higher the storage temperature and humidity of the storage area, the greater the rate of self discharge.

One cell does not boil when charging the battery: what to do?
When one cell in a lead-acid car battery does not boil, this indicates that one of the cells is either not charging or is lagging behind the rest. There are only two reasons. The first is a short man, which cannot be corrected by adequate methods. The second reason is imbalance due to selective sulfation. It is treated by training or battery ...
Why is my battery not holding its charge?
Lead acid vehicle batteries that are never fully recharged can also suffer from acid stratification. This is where the acidic part of the electrolyte becomes concentrated at the bottom of the battery which causes two issues. Firstly it means there is less acid in direct contact with the plates which makes it less effective in doing its job and ...

What is a Lead-Acid Battery?
The acid reacts with the lead plates to generate an electrical current. When the battery is fully charged, the acid is concentrated, and it has a specific gravity of around 1.265. As the battery discharges, the acid becomes less concentrated, and its specific gravity drops. When the battery is fully discharged, the acid has a specific gravity of around 1.120. Battery Casing. …

Battery characteristics, problems and fault Diagnosis
If a battery is subjected to deep discharging (greater than 35%) and rapid charging the process is accelerated. Additionally if the recharge does not recover the discharge cycle in full, the battery will exhibit loss of performance and concentration of the acid can occur between plates which can lead to corrosion and loss of performance.
