NDARY CELLS 917 Charging. When the plates have been properly formed the processes ofcharging and discharging may be represented approximately by thefollowing equations : Positive Plate.PbS04 + S04 + 2H20 = Pb02 + 2H,S04. Negative Plate.PbS04 + H2 = Pb + H2S04. Positive Plate.Pb02 + H2S04 + H2 =… … Fig. 8f>:i. Secondary cells. During discharge, sulphuric acid disappears and the density of thelectroly.te falls. Observation of the density of the acid givesbhe best indication of the condition of the cell. It should notexceed 1-21 when the cell is fully charged, nor fall below 1-15 when>.t…
