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. Eventually, the battery will become completely discharged and will need to be recharged before it can be ...
Effects of Sulfation and Acid Stratification. Sulfation occurs when lead sulfate crystals form on your battery''s plates, which usually happens if a battery is left undercharged or at a partial state of charge for an extended period. It hampers your battery''s ability to charge and discharge fully. Acid stratification describes the situation where the battery acid …
