AIRCRAFT STARTING BATTERIES
“SAISAKTHI” aircraft starting batteries are specially designed to withstand the rigorous working condition in airbase. These batteries have very high efficiency to deliver the required energy every time on time.

 

HIGHLIGHTS

Robust construction

High starting power
Low antimony – selenium alloy offers low maintenance.
Low gassing
High corrosion resistance
Low self discharge.


FEATURES

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. These grids serve to conduct the current to and from the active material of the positive and negative plate. The grids are made of an alloy consisting essentially of lead, antimony, selenium, arsenic and tin. The low antimony alloy facilitates low gassing & low self discharge.
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. This is designed with maximum surface area to provide more power & higher sustained voltage.
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. The active materials also contain expanders to prevent the spongy lead from contracting and reverting to solid inactive state during the life of the battery. High efficiency design provides perfect balance with positive to give maximum performance
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. Micro porous ribbed PVC construction facilitates maximum electrolyte contact. High porosity ensures negligible internal resistance. P.E. separators which have a very high porosity and very low internal resistance are also used.
Containers
The battery containers are of the moulded type, made of hard rubber.
