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.

Today, we pause to remember the U.S. service members who gave their lives in service to our country.

Memorial Day is a moment for gratitude, reflection, and respect. We honor the courage of those who made the ultimate sacrifice, and we hold in our thoughts the families and loved ones who carry their legacy forward.

May we never take their service, sacrifice, or the freedoms they protected for granted.

Outdoor heat has a cost.

As communications networks expand deeper into neighborhoods and edge environments, more backup power systems are operating in outdoor cabinets where temperature is not controlled.

Over time, sustained elevated operating conditions can increase energy consumption, accelerate battery degradation and influence replacement interval stability. Those costs are not always visible at purchase. They often show up later through increased energy use, labor, travel and repeat maintenance visits, especially in hard-to-reach network locations.

To help operators better manage these challenges, EnerSys has launched the AlphaCell™ 4.0HP+ battery, engineered for outside plant deployments across North America.

Built on proven Thin Plate Pure Lead (TPPL) technology, AlphaCell™ 4.0HP+ batteries incorporate an integrated catalyst designed to improve electrochemical stability during float operation, help moderate float current demand and support more predictable performance over the battery’s service life.

Supported by an extended six-year warranty, AlphaCell™ 4.0HP+ batteries are designed for distributed outdoor, network-critical applications operating under variable environmental conditions.

We’re proud to share a closer look at the impact behind our recent RISE PA grant.

At our Horsham, Pennsylvania facility, this investment supports targeted upgrades designed to improve energy efficiency and operational performance, including:
• Enhanced building automation for smarter HVAC and lighting control
• High-efficiency rooftop heat pump systems
• LED lighting upgrades
• A new variable speed air compressor

These improvements are expected to deliver more than $45,000 in annual energy savings.

This is what progress looks like—focused investments that strengthen our operations and deliver real results.

Thank you PA DEP Secretary, Jessica Shirley, for your visit to our Horsham, PA Plant to see our facility.
