When a lead storage battery is recharged, it undergoes reverse chemical reactions from those that occur during discharge. In this phase, electrical energy is consumed to transform lead sulfate (text{PbSO}_4) back into its original forms: lead dioxide (text{PbO}_2) at the cathode and sponge lead (text{Pb}) at the anode.
This is the reason why lead-acid batteries must be charged as soon as possible (to prevent the building up of lead sulfate). Charging of the lead batteries is usually done by providing an external current source. A plug is inserted which is linked to the lead-acid battery and the chemical reaction proceeds in the opposite direction.

Electrochemical Reactions. When a lead-acid battery is charged, a chemical reaction occurs that converts lead oxide and lead into lead sulfate and water.
