During the discharge process, the lead-acid battery generates a current that can be used to power an electrical device. However, as the battery discharges, the concentration of sulfuric acid decreases, and the voltage of the battery drops. A higher load or a higher temperature will cause the battery to discharge more quickly. Charge Process

Learn MoreDeeply discharging a lead acid battery damages it so doing that for the sake of doing that doesn't sound like a good idea. And if you have some reasonable usecase for that then you'd better explain so that answers can address your actual problem. A discharged lead-acid battery can hardly be considered safe.
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.
While charging a lead-acid battery, the following points may be kept in mind: The source, by which battery is to be charged must be a DC source. The positive terminal of the battery charger is connected to the positive terminal of battery and negative to negative.
The following are the indications which show whether the given lead-acid battery is fully charged or not. Voltage : During charging, the terminal voltage of a lead-acid cell When the terminal voltage of lead-acid battery rises to 2.5 V per cell, the battery is considered to be fully charged.
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).
Specifically, if you want to fully discharge a typical car battery (12V, 60 A hr), all you need is a 20 ohm, 10 W resistor (or equivalent), and connect it across the battery terminals. Leave it connected for about 4 days, and with a voltmeter verify that the voltage is zero.
