What Harm Does Overdischarge Do To The Battery?

During the discharge process of the battery, the positive active material and the negative active material are gradually converted into PBSO4 with a large resistance, and the sulfuric acid in the electrolyte is consumed, and the internal resistance gradually increases. A lot of heat, and the amount of sulfuric acid in the battery is very small, the concentration of sulfuric acid decreases very low during overdischarge, and the solubility of PBSO4 increases greatly, so it is easy to form a thick and hard PBSO4 crystal on the plate, that is, "irreversible sulfation" greatly. It is especially harmful to weaken the charging acceptance ability of the battery.
