Defence applications need batteries to work in very hostile conditions like long storage, exceptionally harsh environments, altitudes. Most important is these are mission critical applications. Defence applications demand powerful, highly engineered solutions—combining innovative design, advanced materials, and precision manufacturing. These systems must also adhere to rigorous international standards, including MIL-STD-810, MIL-STD-461G, MIL-PRF, IEC, UN38.3, UL, and NRTL certifications. Beyond technical excellence, supply chain resilience is critical: ensuring not only consistent quality and cost-efficiency but also uninterrupted availability, even amid global challenges such as armed conflict or geopolitical instability.

SES was originally established to service military batteries, and over the course of more than 35 years, the company has significantly expanded its capabilities. Today, a substantial proportion of SES’s operations is dedicated to the design and manufacture of advanced battery and charging systems for defence and security applications, where adherence to stringent military-grade performance standards is essential. SES has cultivated a robust portfolio of products that embody the latest advancements in battery and charger technology, engineered to deliver reliable power in mission-critical scenarios and the most challenging operational environments.
