Lead acid Battery Charging procedure-
To charge lead-acid batteries, the cell is disconnected from the load id connected to a D.C. charging supply of the correct voltage. The positive of the charging supply is connected to the positive side of cell, and the negative of the .charging supply to the negative of a cell. Flow of current from the charging source reverses the discharge action of the cell: thus lead sulphate on the plates is broken down. The sulphate goes back into Solution as sulphate ions (SO4ˉˉ) leaving the plates as pure lead. Water in the electrolyte breaks down returning hydrogen ions (H+) to the solution and allows the oxygen to recombine with the lead of the positive plate and form lead peroxide (PbO2).
