“SAKTHI” automotive batteries are specially designed to withstand the rigorous working condition in passenger cars, trucks, tractors, automotive and other applications.
Selectional view of automotive battery:
High starting power
Low antimony – selenium alloy offers low maintenance
High corrosion resistance
Low self discharge
High life cycle characteristics
Grids: The plates of the lead acid battery consists of an electrically – conducting grid framework, in the mesh of which the active materials are incorporated by an electro-chemical process. The grids are made of an alloy consisting essentially of lead, antimony, selenium, arsenic and tin.
Positive Plates: The positive active material is in the form of lead peroxide. This is a dark brown crystalline material which consists of very small grains or particles. It provides a high degree of porosity and allows the electrolyte to penetrate the plates freely.
Negative Plates: The negative active material is in the form of porous mass of lead in spongy form through which the electrolyte can penetrate freely.
Separators: If positive plate touches a negative plate, all plates in the cell lose their stored energy. Therefore, a sheet of non-conducting material called a separator is inserted between the positive and negative plates.
Containers: These are of the moulded type, made of hard rubber or plastic.
