Lead batteries operate in a constant process of charge and discharge When a battery is connected to a load that needs electricity, such as a starter in a car, current flows from the battery and the battery then begins to discharge. As a battery begins to discharge, the lead plates become more alike, the acid becomes weaker and the voltage drops.
When the battery discharges, the lead plates react with the electrolyte solution to produce lead sulfate and release electrons. When the battery is charged, the process is reversed, and the lead sulfate is converted back to lead plates and sulfuric acid. One of the significant limitations of lead-acid batteries is their low energy density. They have a low …
