Operation of Lead Acid Batteries
3.1. Principles of operation. Gaston Planté, following experiments that had commenced in 1859, was the first to report that a useful discharge current could be drawn from a pair of lead plates that had been immersed in sulfuric acid solution and subjected to a charging current [1].Later, Camille Fauré proposed [2] the concept of the pasted plate. . …

A typical lead acid battery cell has two plate types, one of lead and one of lead dioxide, both in contact with the sulfuric acid electrolyte as either a liquid, absorbed in a mat (AGM), or a gel. The lead dioxide (PbO 2 ) plate reacts with the sulfuric acid (H 2 SO 4 ) electrolyte resulting in hydrogen ions and oxygen ions (which make water) and lead sulfate (PbSO 4 …
Operation of Lead Acid Batteries
When the battery is connected to the external circuit for discharge, sulfuric acid will react with the active substances on the positive and negative plates to form the compound "lead sulfate". The longer the discharge time is, the thinner the sulfuric acid concentration is, the less the "liquid" in the battery, and the lower the voltage at ...
One of the key parameters of battery operation is the specific gravity of the electrolyte. Specific gravity is the ratio of the weight of a solution (sulfuric acid in this case) to the weight of an equal volume of water at a specified temperature. This measurement is usually measured using a Hydrometer. The specific gravity of a fully charged GB …
