Normally battery manufacturer provides the proper method of charging the specific lead-acid batteries. Constant current charging is not typically used in Lead Acid Battery charging. Most common charging method used in lead acid battery is constant voltage charging method which is an effective process in terms of charging time.
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.
Typical sealed lead acid battery charge characteristics for cycle service where charging is non-continuous and peak voltage can be higher. Typical characteristics for standby service type battery charge. Here, charging is continuous and the peak charge voltage must be lower.
If we take the same 12V 160Ah example, then the maximum supply current is 20A, so the maximum safe charging current is the 20A. We should not increase or provide large charging current as this will result in heat and increased gas generation. Watering is the most neglected maintenance feature of flooded lead-acid batteries.
Discharging of a lead acid battery is again involved with chemical reactions. The sulfuric acid is in the diluted form with typically 3:1 ratio with water and sulfuric acid. When the loads are connected across the plates, the sulfuric acid again breaks into positive ions 2H+ and negative ions SO 4.
Over-discharging a lead-acid cell, like over-charging, can severely shorten the service life of the cell. The circuit moni-tors the discharging of the battery and disconnects all load from the battery when its voltage reaches a specified cutoff point.
