With the continuous development of new technology and the continuous development and deepening of application fields, people put forward a higher performance and use characteristics requirements for chemical power supply. The traditional lead-acid battery can not meet the requirements of no maintenance, all-round work, small self discharge, long life, frequent cycle discharge, convenient and fast use. Deep cycle batteries are gradually emerging, and begin to replace the traditional lead-acid batteries. They are also marching into some traditional application fields that need frequent deep cycle discharge, and become a new generation of lead-acid batteries. At present, deep cycle batteries are widely used because of their excellent characteristics.

How does deep cycle battery work?

The charging and discharging process of the deep cycle battery is realized by an electrochemical reaction. During the discharge of the lead-acid battery, HSO4- ions migrate to the negative plate and react with Pb on the negative plate. The formed Pb2+ ions react with SO42- ions to form PbSO4 on the surface of the negative plate and release electrons. On the positive plate, PbO2 obtains electrons from the external circuit, which are reduced to H2O and Pb2+ ions. Pb2+ ions react with SO42- ions to form PbSO4 deposited on the electrode. As the discharge proceeds, H2SO4 is consumed and H2O is generated, which leads to the decrease of electrolyte concentration in the battery. With the increase of cell internal resistance, the electromotive force decreases. H2SO4 not only conducts current, but also participates in battery reaction. When the battery is fully discharged, the positive plate and negative plate are basically transformed into PbSO4. Because the active substances at both poles are transformed into PbSO4 after discharge, it is called "bisulfation" theory. In the process of battery charging, Pb2+ on the surface of the positive plate releases electrons and acts on the electrolyte to form PbO2. Pb2+ on the surface of the negative electrode acquires foreign electrons, which makes PbSO4 transform into active material. At the same time of charging, H2SO4 is released continuously, which makes the sulfuric acid density of electrolyte increase continuously, gradually return to the original concentration, and the electromotive force increases.
