Exide Industries is a storage battery producing company in India. It manufactures automotive and industrial lead-acid batteries. It has plants in India and Sri Lanka.[1]


The company was incorporated as Associated Battery Makers (Eastern) Ltd., on 31 January 1947 under the Companies Act, 1913 to purchase all or any of the assets of the business of manufacturers, buyers and sellers of and dealers in and repairers of electrical and chemical appliances and goods carried on by the Chloride Electric Storage Company (India) Ltd, in India, since 1916 with a view thereto to enter into and carry into effect (either with or without modification) an agreement which had already been prepared and was expressed to be made between the Chloride Electric Storage Co (India) Ltd on the one part and the company of the other part. The name of the company was changed to Chloride India Ltd on 2 August 1972. The name of the company was again changed to Chloride Industries Ltd. vide fresh Certificate of Incorporation dated 12 October 1988. The company was further changed to Exide Industries Ltd. on 25 August 1995.

The company manufactures the widest range of storage batteries in the world[citation needed] from 2.5 Ah to 20,400 Ah capacity, covering the broadest spectrum of applications. The company has seven factories located across the country – two in Maharashtra, two in West Bengal - Shamnagar (Mother plant) & Haldia, one in Tamil Nadu Hosur, one in Haryana and one in Uttarakhand. The company’s predecessor carried on their operations as import house from 1916 under the name Chloride Electrical Storage Company. Thereafter, the company started manufacturing storage batteries in the country and have grown to become one of the largest manufacturer and exporter of batteries in the sub-continent today. Exide separated from its UK-based parent, Chloride Group Plc., in 1989, after the latter divested its ownership in favour of a group of Indian shareholders.
