... lead-acid battery, a voltage is produced when reaction occurs between the lead electrodes and sulfuric acid and water electrolytes . The schematic view of lead-acid battery is depicted in Figure 2.
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 electrical energy is stored in the form of chemical form, when the charging current is passed. lead acid battery cells are capable of producing a large amount of energy. The construction of a lead acid battery cell is as shown in Fig. 1. It consists of the following parts : Anode or positive terminal (or plate).
Construction, Working, Connection Diagram, Charging & Chemical Reaction Figure 1: Lead Acid Battery. The battery cells in which the chemical action taking place is reversible are known as the lead acid battery cells. So it is possible to recharge a lead acid battery cell if it is in the discharged state.
Following are some of the important applications of lead – acid batteries : As standby units in the distribution network. In the Uninterrupted Power Supplies (UPS). In the telephone system. In the railway signaling. In the battery operated vehicles. In the automobiles for starting and lighting.
Brief Description. Most lead acid battery desulfators out there use a flyback design with inductors. While this does work, the inductor can only hold so much energy each pulse. If the battery has a high resistance, that energy won’t be absorbed very well and will show up as a very high voltage spike on an oscilloscope.
