EnerSys is a manufacturer of batteries for motive power, reserve power, aerospace, and defense applications.[1]


EnerSys operates in over 100 countries worldwide, with 23% of the market share worldwide with US $2.283 billion in revenue.[2]

Headquartered in the United States, with regional headquarters in Europe and Asia, EnerSys employs over nine thousand people and operates 32 manufacturing and assembly facilities world-wide. EnerSys traces its corporate roots back to the formation of The Electric Storage Battery Company (ESB) in the late 19th century. The corporate predecessors of EnerSys came out of ESB's industrial battery business.

In 2008, EnerSys significantly broadened its product support for the renewable energy market sector with the launch of its EcoSafe battery product line EcoSafe batteries, which use lead, nickel and lithium technologies. They were developed specifically for renewable energy storage applications, including solar power, wind power and other electricity-generation alternatives.[3]




Their brands for motive power include: Hawker, Ironclad, General Battery, Fiamm Motive Power, Enforcer, Legacy. Material handling equipment, ranging from small walk-behind trucks in food stores, to massive narrow aisle equipment in the most advanced logistics hubs, represents a large and growing industry. These markets are supported by global trade, advanced supply chains, and further migration from internal combustion engine trucks to battery powered trucks. The shift towards more electric trucks is supported by further expansion with AC drives and battery developments like low maintenance designs, fast-charge technology, unique energy packs like Thin Plate Pure Lead (TPPL) batteries and lithium-ion solutions.


Their brands for reserve power are as follows: Powersafe, Datasafe, Cyclon, Genesis. Dependence on continuous power has never been more critical with integrated networks and systems, yet worldwide investments in power generation and distribution continue to lag behind the growing demand. The Reserve Power products are based on several technologies: lead, nickel and lithium-ion. They also offer fuel cells. In response to ever-evolving telecommunication networks’ technologies and ever-challenging operating conditions, EnerSys has launched the ground-breaking EON Technology to enhance the cyclic performance without any detrimental effect on product service life.
