Sealed Energy Systems

About Us

In the year 1990, Sealed Energy Systems took up the challenge of technology development in the field of Sealed Rechargeable Batteries. After extensive R&D, the technology of SLA batteries was developed and commercial production started in 1993. Under the proficient headship of our experts, the company has acquired a noteworthy position. Over 20 years of handwork, SES has emerged as a customized battery manufacturer, exporter and supplier in India. Today we expertise in all battery chemistries whether it be Sealed Lead Acid (SLA), Nickel Metal Hydride (NIMH), Nickel Cadmium (NICD) or Li-ion.
