As data centers support higher-density infrastructure and AI-driven workloads, power systems need to perform predictably under real-world conditions.
EnerSys has introduced the DataSafe Noir™ lithium-based energy storage system, engineered to help operators manage power behavior under high-variability load conditions. Designed as an integrated system, DataSafe Noir™ energy systems support controlled performance, compact deployment, and greater operational confidence in demanding data center environments.
Compared to publicly available specifications for leading lithium systems, DataSafe Noir™ energy systems deliver more than 2x output power and over 1.7x greater energy and capacity, helping operators improve utilization of data center floor space.
“The industry has spent years optimizing batteries — increasing energy density and reducing footprint,” said John Gagge, Vice President of Business Development, Energy Systems at EnerSys. “But the real issue is how the system behaves under stress, particularly in high-density environments. The DataSafe Noir™ system is designed to give operators control over that — not just improve performance on paper.”
Backed by EnerSys’ global installation, commissioning, and service network, DataSafe Noir™ systems expand our data center portfolio with an advanced lithium-based option for critical power applications.
