Founded in Ambala. Built for India.
SES Batteries was founded in 1991 in Ambala Cantt, Haryana — a city that sits at the intersection of India's defence corridor and its expanding industrial heartland. We started as Sealed Energy Systems with a single conviction: that India deserved a domestic battery manufacturer capable of building to global quality standards, not just claiming to.
The first decade was about foundation — processes, people, and the discipline to get things right before getting them fast. By the 2000s, we had earned the trust of sectors where a battery failure carries real consequences: defence, industrial, and healthcare.
Today, SES is a specialist. We manufacture in two verticals — medical healthcare batteries and OEM Smart Li-ion battery packs — and we go deep in both.
Engineered Here. Validated Here. Shipped Reliable.
At our facility in Ambala Cantt, every battery pack is built through the same disciplined process: cell selection and batch verification, precise assembly, BMS configuration, protection circuit validation, and final clearance against your device's actual load profile. As a dedicated lithium battery company in North India, we work across 18650, 21700, pouch, and prismatic cell formats, and we do not outsource a single step of it.
We do not dispatch a pack we have not validated against your device's actual load profile. That is not a marketing claim, it is how a battery company in Haryana, India earns 33 years of repeat business.
Our Products
Batteries Where Failure Is Not an Option
When a ventilator switches to backup power mid-procedure, or a portable patient monitor follows a surgeon into the operating theatre, the battery inside must perform without hesitation. SES engineers medical-grade Li-ion packs to IEC 62133 standards, with full traceability and zero tolerance for variance. This is what being a battery manufacturer in Ambala Cantt with ISO 13485 certification actually means in practice.
Custom-Built for Your Product. Not Adapted from a Catalogue.
If you are an OEM product company, you deserve a battery that was engineered for your device, not a generic cell assembly labelled to fit. SES designs and manufactures custom Li-ion battery packs with integrated BMS, tailored capacity, and scale-ready production. As an industrial battery company in Ambala, we serve clients across the Delhi NCR, Punjab, and Haryana manufacturing corridor with low MOQ and full documentation support.
Our Location Advantage
Ambala Cantt is a deliberate address. Within practical reach of Delhi NCR, Chandigarh, and the Punjab-Haryana industrial corridor — one of the most active manufacturing belts in northern India.
