A lead-acid battery is a electrical storage device that uses a reversible chemical reaction to store energy.
A lead-acid battery is composed of a series of plates immerse in a solution of sulfuric acid.
When the battery is discharged (when it is subjected to an electrical load), acid from the elecrolyte combines with the active plate material. When a battery is recharged, the opposite occurs: the lead sulfate reverts back to active material, and the electrolyte becomes more acidic with a higher specific gravity. During discharge, the lead dioxide (positive plate) and lead (negative plate) react with the electrolyte of sulfuric acid to create lead sulfate, water and energy. Many new competitive cell chemistries are being developed to meet the requirements of the auto industry for EV and HEV applications. Even after 140 years since its invention, improvements are still being made to the lead acid battery and despite its shortcomings and the competition from newer cell chemistries the lead acid battery still retains the lion's share of the high power battery market.

Quality is never an accident; it is always the result of high intention, sincere efforts, intelligent direction and wise choice of alternatives and skillful execution. When the switch is closed and the battery is supplying current, 2 electrons are pulled away from the Lead atom: they’re attracted to the positive side of the battery. At the same time, the Lead ion (Pb+2) reacts with the Sulfate part of the Hydrogen Sulfate ion (HSO4-), leaving a Hydrogen ion behind.
When the Lead and Sulfate combine they form Lead Sulfate which precipitates onto the electrode surface.  Meanwhile, the electrons pass through the light bulb, heat the filament, and provide illumination! The Lead (Pb2+) reacts with the Hydrogen Sulfate ion (HSO4-), releasing a Hydrogen ion, and the aqueous Oxygen ions react with the Hydrogen ions in solution. Notice that since the electrons have passed through the bulb, no further light is supplied.  In an actual reaction, there are many, many millions of electrons so the battery would supply light for much longer. The Oxygen ions and Hydrogen ions combine (what do they form?), and the Lead and Sulfate ions also combine.  See what they become in the next drawing!
As the battery continues to operate, the acid in the electrolyte is slowly replaced by water.  When it’s all water the battery is dead!
Fortunately this reaction is reversible.  If we pass a direct current through the cell in the opposite direction, the Lead Sulfate dissociates back into Lead and Sulfate ions and the Water dissociates back into Oxygen and Hydrogen.  Lead Oxide is restored on the positive electrode and pure Lead on the negative side…and we can use it all over again!

It uses a combination of lead plates or grids and an electrolyte consisting of a diluted sulphuric acid to convert electrical energy into potential chemical energy and back again. Each plate consists of a grid upon which is attached the active material (lead dioxide on the negative plates, pure lead on the positive plates.) All of the negative plates are connected together, as are all of the positive plates. Niclas has been living and working in East and South Asia for over 7 years, including Mainland China, Taiwan, India and Iran, and has worked on and implemented multiple clean energy and solar rural electrification projects for IGOs and NGOs worldwide, such as UNIDO and Grameen Shakti. The electrolyte of lead-acid batteries is hazardous to your health and may produce burns and other permanent damage if you come into contact with it.
The electrolyte become less acidic in the process, and the specific gravity of the solution drops. However, if a starter battery is discharged deeply (more than 20-25% depth of charge), its plates can be permanently damaged and the lifetime of the battery greatly reduced. Deep cycle batteries have fewer thicker lead plates, and so cannot discharge energy so quickly, but can be cycled deeply and recharged many times without damaging the battery.
