The global data center lithium-ion batteries market was valued at USD 2.18 billion in 2025. The market is estimated at USD 2.64 billion in 2026 and is expected to reach USD 11.45 billion by 2036, growing at a CAGR of 15.8% from 2026 to 2036. This report assesses lead acid replacement, rack storage content, energy versus power uses, total cost of ownership, fire safety and insurance, the replacement cycle, pricing, competition, and growth opportunities.
The market covers lithium-ion battery systems installed in data centers to keep critical IT load running during a power interruption and to support power quality. It includes battery cabinets and racks supplied with uninterruptible power supply (UPS) systems, modular battery modules with their management systems, rack-level battery backup units (BBUs) placed inside the IT rack, and containerized or outdoor enclosures for modular and prefabricated sites, built on lithium iron phosphate (LFP), nickel manganese cobalt (NMC), and lithium titanate (LTO) chemistries. Related battery management, fire protection, installation, monitoring, and replacement services are also in scope.
NVIDIA has outlined an 800-volt direct current (DC) power design for IT racks of 1 MW and above starting in 2027, tied to its Kyber systems, with energy storage built in to absorb sub-second GPU power swings; according to NVIDIA, 800-volt busways deliver 85% more power over conductors of equal size and cut copper use by 45% against 415-volt AC distribution, and the Vera Rubin NVL144 specification includes 20 times as much energy storage at the rack level. Demand for protected load is also rising quickly, as Vertiv reported second-quarter 2026 net sales up 24.1% year over year and a year-end 2025 backlog of USD 15.0 billion, up 109%. Supplier returns remain modest, with EnerSys reporting an Energy Systems operating margin of only 5.2% for the fiscal year ended March 31, 2026.
Fire codes, stationary storage installation standards, and large-scale fire testing set limits on the amount of lithium per room, separation distances, and suppression, and insurers often apply stricter conditions than the code, so fire engineering now shapes battery room size and, in some jurisdictions, caps lithium content. Supercapacitors are a direct competitor for rack-level transient support, as Eaton's 800-volt DC reference architecture developed with NVIDIA and shown at the 2025 Open Compute Project Global Summit uses supercapacitor ride-through storage. Cell supply is concentrated and exposed to tariffs and export controls, while long qualification cycles and thin hardware margins limit supplier returns.
Rack-level BBUs sized for runtime in accelerated computing platforms are a major opportunity, as is early qualification within 800-volt DC reference architectures while they are being defined ahead of volume rollout from 2027. The first large wave of lithium-ion UPS batteries is also reaching replacement age, creating recurring battery-only sales that favor suppliers with backward-compatible modules. Peak shaving offers longer-term upside where rules and warranties allow cycling of backup assets. Key trends include the shift of energy storage from the facility to the rack, the split of energy and power roles across lithium-ion, LTO, high-power cells, and supercapacitors, and closer integration of battery monitoring with facility and power control systems.
By chemistry, the data center lithium-ion batteries market is segmented into lithium iron phosphate (LFP), nickel manganese cobalt (NMC), lithium titanate (LTO), and other chemistries. Lithium iron phosphate is expected to account for the largest share in 2026 and to grow at the highest CAGR during the forecast period, owing to its stable thermal behavior and later onset of thermal runaway than nickel-based cells, which matters most where fire codes and insurers govern installation, its longer cycle life, its freedom from cobalt and nickel, and the large manufacturing capacity dedicated to it for stationary use. NMC should grow more slowly, mainly where energy density in a tight footprint matters most. Lithium titanate is set to grow from a small base in uses that need fast charging and discharging and an extremely long life, complementing LFP.
By product, the data center lithium-ion batteries market is segmented into UPS battery cabinets & racks, rack-level battery backup units (BBUs), modular battery modules, and containerized & outdoor battery enclosures. UPS battery cabinets & racks are expected to account for the largest share in 2026, as facility- and row-level UPS systems need batteries sized for several minutes at full load, and replacing VRLA strings in these systems is the single largest source of lithium-ion demand in data centers. Rack-level battery backup units are expected to grow at the highest CAGR, as storage moves closer to the load with rising rack power and transient severity, new platform specifications carry far more rack-level storage than earlier ones, and higher-voltage DC reference designs include storage as a core element. Containerized & outdoor enclosures should grow strongly with modular construction.
By application, the data center lithium-ion batteries market is segmented into uninterruptible power supply (UPS) backup, rack-level ride-through & transient support, peak shaving & demand management, and other applications. UPS backup is expected to account for the largest share in 2026, because facilities need minutes of full-load autonomy to transfer to generators, lithium-ion is the best-suited technology for that role, and a large installed base of UPS systems requires battery capacity. Rack-level ride-through & transient support is expected to grow at the highest CAGR, supported by storage built into higher-voltage DC architectures to handle load spikes and sub-second swings and by rising storage content per rack. This growth is shared with supercapacitors, so lithium-ion captures the part of the application that needs runtime rather than instant power.
By runtime, the data center lithium-ion batteries market is segmented into under 5 minutes, 5 to 15 minutes, and above 15 minutes. The 5 to 15 minutes segment is expected to lead in 2026, as UPS autonomy in most designs is sized around the time needed to start generators and transfer load, and most installed battery capacity follows that rule. Under 5 minutes is expected to grow at the highest CAGR, driven by rack-level units that carry a rack through a transfer or allow orderly shutdown, short-duration storage within DC power architectures, and the lower energy per unit that makes installation within the rack practical. Above 15 minutes stays limited to sites without reliable on-site generation.
By data center type, the data center lithium-ion batteries market is segmented into hyperscale & cloud, AI & high-performance computing (HPC) facilities, colocation, and enterprise & edge. Hyperscale & cloud is expected to account for the largest share in 2026, given the capacity these operators build and run, their standardization on lithium-ion for new builds, and the buying power that lets them qualify battery systems and cells directly. AI & HPC facilities are expected to grow at the highest CAGR, as their rack power raises both total protected load and storage per rack, accelerated computing creates severe load transients, and these sites are first to adopt higher-voltage DC designs with built-in storage. Colocation demand should also rise quickly as tenants with accelerated computing needs lease powered space.
North America is expected to lead the global data center lithium-ion batteries market in 2026, supported by large-scale hyperscale and AI construction, the standardization of major operators on lithium-ion for new builds, a strong base of power infrastructure and battery suppliers such as EnerSys, Eaton, East Penn Manufacturing, and Vertiv, and work on new DC reference designs with partners in the region. Vertiv reported Americas net sales growth of 29.2% in the second quarter of 2026, against 1.7% in EMEA. In Europe, new builds in Ireland, Germany, the Netherlands, and the Nordics, efficiency and sustainability reporting rules, and suppliers such as Schneider Electric, ABB, and Legrand support a significant share, though growth is held back by slower infrastructure demand and conservative fire code and planning rules in several metro markets.
Asia-Pacific is expected to grow at the highest CAGR during the forecast period, driven by data center construction in China, India, Japan, Malaysia, Singapore, and Australia, the concentration of lithium cell production in China, South Korea, and Japan, where Samsung SDI, LG Energy Solution, CATL, BYD, Narada Power, and Toshiba serve the sector, Huawei and Delta Electronics in data center power, and costs that favor regional supply of complete systems. The Rest of the World holds a limited share, with demand from new capacity in the Gulf states, Brazil, and South Africa, where lithium-ion is specified from the start instead of replacing an installed lead acid base.
Moderate consolidation characterizes the data center lithium-ion batteries market, where UPS and power infrastructure suppliers specify and integrate battery systems, cell and module makers sell to them and to operators directly, and battery specialists compete through system design, safety approvals, and service. Competition centers on energy and power density, cycle and calendar life at data center temperatures, fire test evidence, monitoring integration, compatibility with UPS and DC architectures, cell supply security, warranty strength, and lifetime cost. Leading companies are qualifying storage within DC reference designs, developing rack-level BBUs, offering both energy and power technologies, and securing alternative cell sources. Recent activity includes Eaton's 800-volt DC reference design and EnerSys's lithium data center solution now in customer commissioning.

Market Dynamics
Replacement of valve-regulated lead acid (VRLA) batteries is the base driver of the data center lithium-ion batteries market, as lead acid systems take several times the floor space, need replacing two or three times over a facility's life, tolerate far fewer discharge cycles, and add floor loading and ventilation limits, so operators choose lithium-ion on lifetime cost rather than purchase price. AI data center construction adds protected load at a record pace, and since the required minutes of autonomy do not fall as load grows, battery energy rises with every new megawatt. Storage per rack is climbing even faster, as accelerated computing creates sharp power transients best absorbed near the load, and higher-voltage DC designs build storage into reference architectures instead of ordering it with a UPS.Fire codes, stationary storage installation standards, and large-scale fire testing set limits on the amount of lithium per room, separation distances, and suppression, and insurers often apply stricter conditions than the code, so fire engineering now shapes battery room size and, in some jurisdictions, caps lithium content.
