EnerSys is a manufacturer of batteries for motive power, reserve power, aerospace, and defense applications.
Headquartered in the United States, with regional headquarters in Europe and Asia and operations in 100 countries worldwide, EnerSys employs over nine thousand people and operates 32 manufacturing and assembly facilities worldwide. 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.
