To be a market leader in Lead Acid Batteries by continuous technology Up-gradation through Research and Development work in our DSIR (Govt.of India) recognised R&D Laboratory and providing our esteemed customers with world class quality products, exceeding Customer’s specified requirements and expectations.


To make Lead Acid Technology achieve higher level of excellence through continuous R&D, in respect of all important performance parameters like higher Energy Densiry, Power Density, longer service life, lower maintenance, abuse tolerance, lower foot print etc. and to enable BESS to Power the future with Renewable Energy sources combined with Thermal Plant Grid Energy as a combination to achieve a safer and greener world.


RICO is committed to provide world-class batteries using latest and updated design, technology and manufacturing practices from start to finish.


The Company’s In-house R&D is recognised by Dept. Of Science & Industrial Research (DSIR) under Dept. Of Science & Technology, Govt. of India. The Company has a long term joint research arrangement with IIT, Kharagpur.

The company started R&D activities in 1980 on development of efficient, economic and compact Electric Energy Storage System based on High Energy Density Lead-Acid Storage Batteries for pollution free Electric Vehicle application and also for Non-Conventional Energy Sector application as Battery Energy Storage System (BESS), a unique Energy Storage Power System, for application in Power Utilities for multiple benefits like grid stabilization, better management of system from Generation to Distribution stage, incl. Peaking Power Service, Load levelling etc. Objective of R&D activities was development of economic bulk electric energy reservoir to store surplus/unutilized electric energy as could be generated by power-plants during mid-night/off-peaking hours and re-convert the same to AC Power by high capacity (Mega Watt Range) Advance Power Electronic Convertor for Load Balancing in Power Utility through demand side management in Power System by installation in Electric Sub-Station as Stand-by Power Source for distribution to loads at peak load demand hours etc. and also for Power Line Conditioning. With the technology developed through R&D activities, apart for using the same for BESS operation, the company started manufacturing and marketing HED-LM Lead-Acid Batteries for applications such as Motive Power Source in Battery powered Electric Vehicles/In-plant electric vehicles, Battery powered underground Mining Locomotives and Industrial Batteries. In due course the technology was modified and extended for PLANTE Stationary and Tubular Stationary Batteries. The company has established itself as a pioneer in Technology Development regarding BESS which has very important applications in Power Sector.
