How does a battery recharge?

Aug , 27 2021

The process is the same for all types of lead-acid batteries: flooded, gel and AGM. The actions that take place during discharge are the reverse of those that occur during charge. The discharged material on both plates is lead sulfate (PbSO4). When a charging voltage is applied, charge flow occurs. Electrons move in the metal parts; ions and water molecules move in the electrolyte. Chemical reacti...
