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.
Overcharging a lead acid battery can cause the electrolyte to boil and damage the battery, while undercharging can lead to sulfation, reducing the battery's capacity and lifespan. To determine the recommended charging current for a lead acid battery, you need to know the battery's capacity, voltage, and temperature.
As a general rule, you should use a charging current of 10% of the battery's capacity. For example, a 100Ah battery should be charged with a current of 10A. In conclusion, the recommended charging current for a new lead acid battery depends on the battery capacity and the charging method used.
As a lead-acid battery is charged in the reverse direction, the action described in the discharge is reversed. The lead sulphate (PbSO 4) is driven out and back into the electrolyte (H 2 SO 4). The return of acid to the electrolyte will reduce the sulphate in the plates and increase the specific gravity.
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.
