READING, PA — EnerSys (NYSE: ENS) has launched a lithium-based energy storage platform aimed at helping data center operators manage increasingly volatile power demands driven by artificial intelligence workloads, expanding the company’s position in a market facing growing infrastructure and reliability challenges.
The DataSafe Noir energy storage system, available immediately, is designed for high-density data center environments where operators must manage rapid fluctuations in power consumption from AI applications and other compute-intensive workloads.
The launch reflects a broader shift in the data center industry as operators move beyond traditional considerations such as battery chemistry and runtime toward system-level performance and reliability under dynamic operating conditions.
EnerSys said the platform was engineered to provide predictable power delivery during variable load conditions and to reduce deployment complexity through an integrated system design.
According to the company, the system delivers more than twice the output power and more than 1.7 times the energy and capacity of competing lithium-based systems based on publicly available specifications, potentially allowing operators to reduce the footprint required for backup power infrastructure.
The introduction broadens EnerSys’ portfolio beyond its established DataSafe lead-acid battery products, giving customers a choice between traditional and lithium-based energy storage architectures through a single supplier.
“The real issue is how the system behaves under stress, particularly in high-density environments,” John Gagge, vice president of business development for energy systems at EnerSys, said in discussing the product’s design. “The DataSafe Noir system is designed to give operators control over that — not just improve performance on paper.”
The company said the system is intended for hyperscale and colocation data centers, where deployment speed, operational consistency, and power reliability have become increasingly important as AI adoption accelerates.
EnerSys added that the platform will be supported through its global installation, commissioning, and service network, allowing customers to deploy and maintain the system through a single provider.
