Lead acid batteries find wide application in motor cars, trucks, aircrafts, ships, submarines, railways etc. The major user of the product is in automobiles for providing energy for, ignition of the engine and lighting. In addition it is also used for uninterrupted power supply for computers, emergency lights for houses, telephone systems, power tools, communication devices, as power source for mining and material handling equipments, etc. A new application of the product has emerged today in electric vehicles.

The average life of this battery is approximately 1 to 2 years and therefore these batteries will be needed throughout the life of the vehicle or the machinery’s in use. This indicates that ready market of the product will always be existing.

The lead acid battery enjoys a market share of more than 60 % of the total sales of all kind of batteries in the world. With the phenomenal growth of automobile industries, the demand of such batteries is also increasing at a very fast pace .

Although there are few large scale manufacturers of the product dominating in India, but there are large number of very small scale units manufacturing the product in a most unorganised manner. The product manufactured by them does not qualify the required standards as specified by IS.

PROCESS

The various stages involved in the production of lead acid batteries are :

Grid casting
Mixing, pasting and curing
Forming and drying
Assembly
Testing.

The process developed here places main additives for the production of the paste with incorporation of suitable components such as hard rubber containers, covers, separators are to be procured from standard suppliers. The know-how is very well suited advantageously to the small scale sector.

National Research Development Corporation, a Government of India Enterprise, is a premier technology transfer Corporation with four decades of experience. It has helped establish over one thousand projects in the small and medium scale sector.

The supply of technologies and services to entrepreneurs extend both in the developing and developed countries like USA, Germany, Malaysia, Burma, Nepal, Senegal, Madagascar, Indonesia Philippines, Vietnam, Lanka, Kenya, Brazil, Bangladesh and Egypt.
