SES™: A Decade of Innovation and Expansion (2010–2024)
Between 2010 and 2024, SES™ has emerged as a leading provider of smart Lithium-Ion battery solutions, expanding its capabilities in both standard and custom battery and charger manufacturing. Serving defense, healthcare, and industrial sectors, SES™ offers a diverse product range, including ready-to-fit models, military-grade batteries meeting standards like MIL-STD-810E, and tailor-made designs.
Its advanced facilities in Saha and Ambala Cantt, Haryana, span over 40,000 sq. ft. and support high-volume production, in-house testing, and efficient inventory systems. SES™ also brings in-depth technical expertise in BMS design, automated soldering, and injection mold tooling, backed by ISO 9001:2015 and ISO 13485:2016 certifications.
Key milestones include supplying over 12,000 batteries for ICU ventilators during the 2020 COVID-19 crisis, developing certified military batteries for the Indian Armed Forces in 2015, and enhancing healthcare reliability through large-scale installations in 2013. SES™ continues to drive innovation and quality in smart energy solutions.
SES™ has a rich history of innovation and growth in battery technology, beginning in 1990 with the development of fully indigenous, small-sized valve-regulated sealed rechargeable Lead-Acid batteries in India. By 1993, the company commercially launched these batteries for niche markets, including CNC machines, measuring equipment, dispensing units, and computers. In 1997, SES™ became the sole dependable vendor for oil companies across India, supplying electronic dispensing units.
In 2000, SES™ achieved quality standards in sealed Lead-Acid batteries that matched those of top Japanese manufacturers like Yuasa and Panasonic. The company further expanded its product offerings in 2005 by introducing small-sized, modular 2V batteries (ranging from 1.2Ah to 25.0Ah), with a unique rectangular cell design that allowed the assembly of 4V, 8V, and 10V modules—previously possible only with Ni-Cd or Ni-MH cylindrical cells.
By 2007, SES™ diversified into Nickel-Cadmium and Nickel-Metal Hydride cell packs, unlocking new market opportunities. In 2009, the company developed the first non-magnetic 1.5V R14-size cells for MRI-compatible handheld surgical devices—an innovation still in production today due to ongoing demand.
In 2010, SES™ integrated Lithium-Ion cylindrical and prismatic cell packs, initially using outsourced protection circuits. It soon transitioned to in-house development of protection circuits and expanded its capabilities to include smart gas gauge Battery Management Systems (BMS), marking a significant leap in smart energy solutions.
