About EnerSys
EnerSys is one of the world's largest industrial battery companies. It makes motive power batteries for forklifts and material handling, reserve power batteries for critical backup, and specialty batteries for defense and aerospace, along with chargers and energy systems electronics.
Its AI exposure sits in backup power. Data centers cannot tolerate even momentary power loss, so every facility layers batteries between the grid and its servers. EnerSys supplies UPS batteries under lines like DataSafe, and management has called out data centers as a growth market for its Energy Systems segment as AI capacity gets built.
EnerSys took its current form in 2000, building on battery businesses dating back over a century. It is headquartered in Reading, Pennsylvania, employs about 9,700 people, and trades on the NYSE.
EnerSys in the AI buildout
EnerSys sits in the Data Centers layer and the Power & Energy layer. Every AI facility needs battery backup to ride through grid disturbances until generators start, and EnerSys' DataSafe and related reserve power lines serve exactly that role. Rising rack densities mean each new data center carries more stored energy than the last. Backup power remains a minority end market for EnerSys next to forklifts and telecom, which keeps its buildout exposure Growing rather than Core.
ENS is tracked in Data Centers & Hardware and Power & Energy, rated Growing on the AI Exposure leaderboard.
