When a lead-acid battery is discharged, the electrolyte divides into H 2 and SO 4 combine with some of the oxygen that is formed on the positive plate to produce water (H 2 O), and thereby reduces the amount of acid in the electrolyte. The sulfate (SO 4) combines with the lead (Pb) of both plates, forming lead sulphate (PbSO 4), as shown in
Generally speaking, vented flat plate lead calcium batteries can deliver approximately 50 cycles to a depth of discharge of approximately 80%. Depending upon the manufacturer and model of battery, this correlates approximately to a 4 to 5 hour discharge at the corresponding published discharge current to 1.75 VPC (volts per cell).

Figure 4 : Chemical Action During Discharge When a lead-acid battery is discharged, the electrolyte divides into H 2 and SO 4 combine with some of the oxygen that is formed on the positive plate to produce water (H 2 O), and thereby reduces the amount of acid in the electrolyte.
The sulfate (SO 4) combines with the lead (Pb) of both plates, forming lead sulphate (PbSO 4), as shown in Equation. As a lead-acid battery is charged in the reverse direction, the action described in the discharge is reversed. The lead sulphate (PbSO 4) is driven out and back into the electrolyte (H 2 SO 4).
As a lead-acid battery is charged in the reverse direction, the action described in the discharge is reversed. The lead sulphate (PbSO 4) is driven out and back into the electrolyte (H 2 SO 4). The return of acid to the electrolyte will reduce the sulphate in the plates and increase the specific gravity.
The batteries should be charged in a well-ventilated place so that gases and acid fumes are blown away. The lead-acid battery should never be left idle for a long time in discharged condition because the lead sulfate coating on both the positive and negative plates will form into hard crystals that will be difficult to break up on recharging.
