Customer ServiceLead-Acid Battery Cells and Discharging. A lead-acid battery cell consists of a positive electrode made of lead dioxide (PbO 2) and a negative electrode made of porous metallic lead (Pb), both of which are immersed in a sulfuric acid (H 2 SO 4) water solution. This solution forms an electrolyte with free (H+ and SO42-) ions. Chemical reactions
Customer ServiceElectrolyte also comes in a polymer, as used in the solid-state battery, solid ceramic and molten salts, as in the sodium-sulfur battery. Lead Acid. Lead acid uses sulfuric acid. When charging, the acid becomes denser as lead oxide (PbO 2) forms on the positive plate, and then turns to almost water when fully discharged. The specific gravity of

Customer ServiceBasically, when a battery is being discharged, the sulfuric acid in the electrolyte is being depleted so that the electrolyte more closely resembles water. At the same time, sulfate from the acid is coating the plates and reducing the surface area over which the chemical reaction can take place. Charging reverses the process, driving the sulfate back into the acid. That''s it
Customer ServiceElectrolyte – either as a liquid or a gel – decomposes and is lost as gas. The electrolyte is the agent for chemical reaction – when it is much reduced, or absent, the battery cannot function. These are the principle maladies which cause either an unacceptable loss of capacity in a battery, or a failure to store or release energy at all.
Customer ServiceFor each discharge/charge cycle, some sulfate remains on the electrodes. This is the primary factor that limits battery lifetime. Deep-cycle lead-acid batteries appropriate for energy storage applications are designed to withstand repeated discharges to 20 % and have cycle lifetimes of ∼2000, which corresponds to about five years.

Customer ServiceLead-gel batteries use liquid sulfuric acid as the electrolyte, which is bound with silica. This type is also completely sealed and has a valve that prevents the electrolyte from leaking. This makes them easier to transport and they can also be set up in a lateral position. They are also virtually maintenance-free.
Customer ServiceIn sealed lead batteries, the electrolyte (also diluted sulphuric acid) is contained in a glass-fibre fleece or gel. Hence, there is no need for water refilling and the cells must not be opened. Occasionally occurring hydrogen and oxygen gases are released into the environment via valves in the battery lid.

Customer ServiceThe specific gravity of the electrolyte (measured by means of a hydrometer) is used as an indication of the state of charge of a lead-acid battery. An electrolyte with a specific gravity of 1100 to 1150 is 1.1 to 1.15 times as dense as water. At 1100 to 1150, the cell is completely discharged. When the specific gravity is 1280 to 1300, the
Customer ServiceSLA batteries require specific charging profiles to optimize their performance and longevity. Improper charging, such as overcharging or undercharging, can lead to reduced battery life and capacity. The need for precise charging management adds complexity to the use of sealed lead acid batteries in certain applications. 5. Sulfation
Customer ServiceThe lead acid battery uses lead as the anode and lead dioxide as the cathode, with an acid electrolyte. The following half-cell reactions take place inside the cell during discharge: At the anode: Pb + HSO4– → PbSO4 + H+ + 2e–. At the cathode: PbO2 + 3H+ + HSO4– + 2e– → PbSO4 + 2H2O. Overall: Pb + PbO2 +2H2SO4 → 2PbSO4 + 2H2O.

With proper care a lead—acid battery is capable of sustaining a great many cycles of charge and discharge, giving satisfactory service for several years. Typical ampere-hour ratings for 12 V lead-acid automobile batteries range from 100 Ah to 300 Ah.
In between the fully discharged and charged states, a lead acid battery will experience a gradual reduction in the voltage. Voltage level is commonly used to indicate a battery's state of charge. The dependence of the battery on the battery state of charge is shown in the figure below.
A lead acid battery consists of electrodes of lead oxide and lead are immersed in a solution of weak sulfuric acid. Potential problems encountered in lead acid batteries include: Gassing: Evolution of hydrogen and oxygen gas. Gassing of the battery leads to safety problems and to water loss from the electrolyte.
The lead-acid battery consists negative electrode (anode) of lead, lead dioxide as a positive electrode (cathode) and an electrolyte of aqueous sulfuric acid which transports the charge between the two. At the time of discharge both electrodes consume sulfuric acid from the electrolyte and are converted to lead sulphate.
Periodic but infrequent gassing of the battery to prevent or reverse electrolyte stratification is required in most lead acid batteries in a process referred to as "boost" charging. Sulfation of the battery.
