Lead acid batteries are heavy and contain a caustic liquid electrolyte, but are often still the battery of choice because of their high current density. The lead acid battery in your automobile consists of six cells connected in series to give 12 V. Their low cost and high current output makes these excellent candidates for providing power for automobile starter motors.
The equation should read downward for discharge and upward for recharge. The battery which uses sponge lead and lead peroxide for the conversion of the chemical energy into electrical power, such type of battery is called a lead acid battery. The container, plate, active material, separator, etc. are the main part of the lead acid battery.
In full charge cycle the charge voltage remains constant and the current gradually decreased with the increase of battery charge level. Discharging of a lead acid battery is again involved with chemical reactions. The sulfuric acid is in the diluted form with typically 3:1 ratio with water and sulfuric acid.
The lead acid storage battery is formed by dipping lead peroxide plate and sponge lead plate in dilute sulfuric acid. A load is connected externally between these plates. In diluted sulfuric acid the molecules of the acid split into positive hydrogen ions (H +) and negative sulfate ions (SO 4 − −).

Separators. Anode or positive terminal (or plate): The positive plates are also called as anode. The material used for it is lead peroxide (PbO 2).
The lead acid battery is most commonly used in the power stations and substations because it has higher cell voltage and lower cost. The various parts of the lead acid battery are shown below. The container and the plates are the main part of the lead acid battery.
A lead-acid battery is composed of a series of cells, each of which includes two types of lead plates – one coated with lead dioxide and the other made of sponge lead – submerged in a sulfuric acid solution. This sulfuric acid solution, also known as electrolyte, acts as a catalyst to prompt the chemical reaction that produces electricity.

Definition: The battery which uses sponge lead and lead peroxide for the conversion of the chemical energy into electrical power, such type of battery is called a lead acid battery. The lead acid battery is most commonly used in the power stations and substations because it has higher cell voltage and lower cost.
A lead-acid battery is a rechargeable battery that uses lead and sulphuric acid to function. The lead is submerged into the sulphuric acid to allow a controlled chemical reaction. This chemical reaction is what causes the battery to produce electricity. Then, this reaction is reversed to recharge the battery.
The lead–acid battery is a type of rechargeable battery first invented in 1859 by French physicist Gaston Planté is the first type of rechargeable battery ever created. Compared to modern rechargeable batteries, lead–acid batteries have relatively low energy density spite this, they are able to supply high surge currents.These features, along with their low cost, make them …
A completely charged lead-acid battery is made up of a stack of alternating lead oxide electrodes, isolated from each other by layers of porous separators. All these parts are placed in a concentrated solution of sulfuric acid. Intercell …
When a lead-acid battery is connected to a load, it undergoes a series of electrochemical reactions: During this discharge cycle, lead sulfate (PbSO4) forms on both electrodes, and water is generated as a byproduct. This process releases electrons, which generate an electric current that powers connected devices.
A completely charged lead-acid battery is made up of a stack of alternating lead oxide electrodes, isolated from each other by layers of porous separators.
