Customer ServiceLead-acid batteries are prone to a phenomenon called sulfation, which occurs when the lead plates in the battery react with the sulfuric acid electrolyte to form lead sulfate (PbSO4). Over time, these lead sulfate crystals can build up on the plates, reducing the battery''s capacity and eventually rendering it unusable. Desulfation is the process of reversing sulfation

The lead–acid cell can be demonstrated using sheet lead plates for the two electrodes. However, such a construction produces only around one ampere for roughly postcard-sized plates, and for only a few minutes. Gaston Planté found a way to provide a much larger effective surface area. In Planté''s design, the positive and negative plates were formed of two spirals o

The most common is the SLI battery used for motor vehicles for engine S tarting, vehicle L ighting and engine I gnition, however it has many other applications (such as communications devices, emergency lighting systems and power tools) due to its cheapness and good performance.
Customer ServiceA Lead Acid Battery consists of the following things, we can see it in the below image: A Lead Acid Battery consists of Plates, Separator, and Electrolyte, Hard Plastic with a hard rubber case. In the batteries, the plates are of two types, positive and negative. The positive one consists of Lead dioxide and negative one consists of Sponge Lead.
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.
The container stores chemical energy which is converted into electrical energy by the help of the plates. 1. Container – The container of the lead acid battery is made of glass, lead lined wood, ebonite, the hard rubber of bituminous compound, ceramic materials or moulded plastics and are seated at the top to avoid the discharge of electrolyte.
Pure lead is too soft to use as a grid material so in general the lead is hardened by the addition of 4 – 6% antimony. However, during the operation of the battery the antinomy dissolves and migrates to the anode where it alters the cell voltage. This means that the water consumption in the cell increases and frequent maintenance is necessary.
There may be the following main defects in a lead acid battery. (a) Sulphation. Formation of the lead sulphate layer on positive and negative plate is known as the sulphation. Effects. The capacity, life and the efficiency Of the cell is decreased.
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.
