The Charging begins when the Charger is connected at the positive and negative terminal. the lead-acid battery converts the lead sulfate (PbSO 4) at the negative electrode to lead (Pb) and At the positive terminal, the reaction converts the lead sulfate (PbSO 4) to lead oxide. The chemical reactions revers from discharging process
Charging is the opposite reaction where the conversion of electrical energy in the form of current from an external source is stored as chemical energy in the battery cell. In all the cell types mentioned, the electrochemical reaction for the discharge and recharge of lead-acid batteries is basically the same.
Lead acid charging uses a voltage-based algorithm that is similar to lithium-ion. The charge time of a sealed lead acid battery is 12–16 hours, up to 36–48 hours for large stationary batteries.
This results in the battery being partially recharged quickly, but it requires prolonged charging to obtain a fully charged state. Neither constant current or step charging are ideal for stationary lead-acid batteries, and constant voltage charging is recommended. With constant voltage charging there are two common charging voltage levels:
In all the cell types mentioned, the electrochemical reaction for the discharge and recharge of lead-acid batteries is basically the same. The basic battery cell design has three or more positive and negative plates immersed in an electrolyte that provides a medium for the transfer of electrons between the plates.
To maintain a charge on the cell, the charging voltage must be slightly higher than the OCV in order to overcome the inherent losses within the battery caused by chemical reaction and resistance. For a lead-acid battery, the value above the OCV is approximately 0.12 volts.
Guide to charging Sealed Lead Acid batteries
During a full charge cycle any gasses produced need to be re-combined in a so called ''oxygen cycle''. Oxygen is generated at the positive plates during the latter stages of the charge cycle, this reacts with and partially discharges in the sponge lead of the negative plates.
