EnerSys products and service solutions ensure that modern life keeps moving, even if the power is out.


Extreme storms and catastrophic fires are becoming the “new normal,” with massive impacts on power grid reliability. Our products provide our customers and the communities they serve with the means to manage power demands while providing the security and stability of a consistent power supply. EnerSys delivers dependable backup power for essential services such as cell towers, data centers, electrical grids and hospitals, ensuring power availability, especially when it’s needed most.

EnerSys Energy Systems play a key role in building California's resilience to wildfires

To mitigate wildfires and protect public safety, the California Public Utilities Commission authorized electric utility providers to shut off electric power at certain times if weather and fuel conditions increase the risk of equipment failure and wildfire.

During these shutdowns, telecommunications providers are required to provide backup power for their networks and communications to remain up and running. This ensures that individuals and organizations have access to vital emergency services, 911 access, high-speed data, news and more.

In recent years, the required backup power time increased from 8 hours to 72 hours, obliging telecommunications companies to find new ways to generate power to keep communications and networks up and running when the power is shut off. Rather than relying on diesel fuel generators, multiple telecommunications companies are utilizing custom EnerSys batteries to power over 5,000 power modules in neighborhoods across California to support communications networks regardless of if grid power goes out. EnerSys was uniquely qualified to design, build and install these integrated systems with intelligent, reliable and clean energy storage for each specific use case.

EnerSys is the world’s largest manufacturer of industrial forklift batteries and chargers.


EnerSys propels the global economy by supplying batteries, chargers, and monitoring services, enhancing the reliability and sustainability of a variety of vehicles, including power forklifts, AGVs and trains. Our solutions ensure the timely delivery of critical materials and goods, from vaccines in cold chain trucks to groceries on forklifts. EnerSys storage solutions support decarbonization goals in warehousing and logistics sectors by eliminating the emissions produced by combustion engines, especially if the batteries are charged by renewable electric sources.

Zero-emissions forklifts save money and reduce emissions

Our batteries make electric forklifts more affordable to operate than fossil fuel alternatives. Replacing a diesel or propane forklift with an electric one is also estimated to reduce more than 50% of the emissions (even with electricity fueled by coal).

Added to the savings, some companies can even get paid to switch to electric forklifts. The California Air Resources Board (CARB) issues Low Carbon Fuel Standard credits for the use of electric forklifts. Based on calculations provided by CARB, a large fleet with 20+ forklifts could receive an estimated $100k in credits per year or more!

Based on initial estimates from our 2023 Scope 1, 2, & 3 emissions inventory, the avoided emissions (i.e., the net benefit to the climate) associated with the use of our batteries in electric forklifts (replacing diesel and propane forklifts) on average range between five to ten times the emissions from mining, manufacturing and shipping our batteries, depending on battery model and how clean the electric grid is where the forklifts are used. In some locations, the avoided emissions from using EnerSys batteries reach a 20x net benefit.

EnerSys batteries have accumulated over 6.8 billion operational cell hours in space, all without a single mission failure, proving out of this world reliability.


When readiness and reliability are paramount, EnerSys® batteries are hard at work in the world’s most critical and demanding applications. High performance, low maintenance and long life are the hallmarks of EnerSys products.

Customers worldwide rely on EnerSys batteries for specialized electronic devices, valuing their proven safety and reliability as power sources. The Specialty line of business includes specialty batteries for aerospace and defense applications, premium automotive, security systems, large over-the-road trucks, and medical applications.

Since building the first Lithium-ion (Li-ion) battery to power a satellite, technological breakthroughs from EnerSys have extended satellite operational life and have lengthened the life of space missions to benefit our scientific communities.

To the moon and beyond

An EnerSys battery will be trusted to power the Roman Space Telescope, poised to uncover the secrets of dark energy and dark matter when it launches in the mid-2020s. This telescope is set to follow in the footsteps of the James Webb Space Telescope and aims to measure light from a billion galaxies throughout the mission lifetime in while also performing a microlensing survey of the inner Milky Way to find ~2,600 exoplanets – planets outside of our solar system.

EnerSys batteries powered NASA’s Space Launch System on its inaugural launch of Artemis 1 in 2022 (pictured above). This is the first unmanned Crew Module launch around the moon since the Apollo era. Artemis 1 made history when at its maximum was nearly 270,000 miles away from Earth, breaking the Apollo 13 distance record. EnerSys is proud to be supporting the Artemis program and powering the critical systems enabling the U.S. to return to the moon and beyond.

By coupling fast charging with robust battery storage, EnerSys offers a complete energy system to power an evolving world.


In the first quarter of fiscal year 2024, EnerSys introduced a new line of business called New Ventures, which includes energy storage and management systems for electric vehicle fast charging, utility back-up power, and demand charge reduction.

To combat climate change and achieve net-zero emissions by 2050 globally, it is crucial to make renewable energy more available and reliable. A reliable grid requires electricity from sources like wind and solar to be consistent, despite their natural variability. Our energy storage solutions ensure that power remains dependable, with batteries storing energy when there is excess and making up the difference during high demand.

More than 25 of our top customers have committed to RE100, a global corporate renewable energy initiative bringing together the world’s most influential businesses committed to 100% renewable energy. We are proud to support the ambitious goals of our customers. Demand for energy storage keeps growing and having a secure domestic source for batteries is critical. As such, we are looking to expand our lithium-ion
cell production capacity in the United States.

New Lithium Gigafactory in Greenville, South Carolina

On Feb 14, 2024, EnerSys announced that it selected Greenville, South Carolina to develop a lithium-ion cell gigafactory to advance battery production in the United States. This new factory represents a long-term opportunity that will enable growth and allow EnerSys to optimize cell sizing in battery solutions for its customers, reducing reliance on non-domestic cell suppliers.

EnerSys recently secured a comprehensive incentive package through South Carolina and Greenville County valued at approximately $200 million, which includes a combination of short-term and long-term incentives. The company intends to use a portion of these proceeds, along with the Inflation Reduction Act IRC 45X tax benefits and potential additional federal funding, to make a $500 million investment with the potential to create 500 high-quality new jobs.

The proposed 500,000-square-foot manufacturing plant at the Augusta Grove business park on about 140 acres will focus on producing various lithium-ion cell types for commercial, industrial, and defense uses, targeting an annual output of four-gigawatt hours.
