Press Release
Data Center Battery Market to Reach USD 6,012.6 Million by 2035 at 5.3% CAGR as Lithium-Ion Replaces Lead-Acid
Date : Nov 04, 2026
Pune, India, November 8, 2026 — The global Data Center Battery Market was valued at USD 3,587.4 million in 2025 and is projected to reach USD 6,012.6 million by 2035, growing at a CAGR of 5.3% from 2026 to 2035, according to the latest Data Center Battery Market report by Ameco Research. The market is estimated at USD 3,777.5 million in 2026. Battery volumes are rising much faster than revenue, because lithium-ion cell prices have fallen sharply and each lithium-ion system replaces several generations of shorter-lived lead-acid batteries.
Data center batteries keep servers, storage, and network equipment running when grid power fails or fluctuates. They sit mainly inside uninterruptible power supply (UPS) systems, bridging the minutes until backup generators start, and are increasingly used in battery energy storage systems (BESS) for peak shaving, load balancing, and grid services. The 180-page study covers battery chemistries, capacity classes, data center types, applications, regional demand, and the suppliers competing for this shift.
Data Center Battery Market Size and Growth Outlook
The market is going through a major technology change. Valve-regulated lead-acid (VRLA) batteries still make up the largest installed base, but operators are moving to lithium-ion, mostly lithium iron phosphate (LFP), for longer life, a smaller footprint, and lower total cost of ownership. At the same time, AI training clusters with sharp, fast-changing power demand are turning batteries from passive backup into active power management assets.

What Is Driving Demand for Data Center Batteries?
A Data Center Construction Boom
Cloud computing, AI, streaming, and digital services are driving record hyperscale and colocation capacity additions, and every new hall needs battery backup. Outages can cost operators hundreds of thousands of dollars per hour, so reliable UPS batteries are essential for Tier III and Tier IV facilities.
AI and High-Density Computing
GPU racks need stable, clean power and a fast response to grid disturbances. AI training clusters can swing power demand by tens of megawatts in seconds, and batteries now smooth those swings, protect hardware, and stabilize the grid connection. Industry estimates suggest energy storage linked to AI data centers could reach about 300 GWh of demand by 2030.
Lead-Acid Replacement and Grid Services
Short VRLA lifespans create a steady replacement cycle, and much of it is shifting to lithium-ion. Batteries also help data centers use more solar and wind power, shave peak demand, and earn revenue from grid support programs.
Data Center Battery Market Trends in 2026
- Lithium-ion takes over new builds: Most new hyperscale and colocation halls specify LFP UPS batteries, which offer 10–15 year lifespans, 50–70% smaller footprints, and lower cooling needs than VRLA.
- Medium-voltage UPS and grid ride-through: New medium-voltage UPS systems use batteries to ride through grid faults instead of disconnecting, and around 3 GW of such projects are operating or under construction in the U.S.
- Batteries as a bridge to grid power: Long waits for grid connections are pushing operators to install large on-site BESS. In August 2026, Cummins won its largest BESS contract, a 5 MWh LFP system for a U.S. data center that manages AI load swings.
- Falling LFP cell prices: Large-format 314Ah LFP cells were trading around USD 0.05 per Wh in mid-2026, making lithium-ion cost-competitive with lead-acid over its lifetime.
- Second-life and new chemistries: Repurposed EV batteries and sodium-ion cells are emerging as lower-cost options. In May 2026, Cleantech Energy Company raised USD 40 million to scale storage systems built from second-life EV batteries for data centers.
Challenges
Lithium-ion systems, battery management, and monitoring still cost more upfront, which can deter small and mid-sized operators. Installations must meet fire safety standards such as UL 9540A and NFPA 855, adding design, testing, and insurance requirements. Switching existing halls from lead-acid can require changes to UPS, cooling, and safety systems, while dependence on lithium, graphite, and cell manufacturing in a few countries exposes buyers to price swings and trade restrictions. Growing battery volumes also need recycling and end-of-life solutions.
Segment Analysis
By Battery Type
| Battery Type | Share (2025) | Key Highlights |
|---|---|---|
| Lead-Acid (VRLA) | 44.3% | Lowest upfront cost; large installed base; 3–6 year life |
| Lithium-Ion | 35.8% | Fastest-growing; 10–15 year life; smaller footprint |
| Nickel-Based (NiZn, NiCd) | 12.4% | High power density and wide temperature tolerance |
| Others (Sodium-Ion, Flow) | 7.5% | Emerging low-cost and long-duration options |
Lithium-ion is expected to become the largest chemistry within the forecast period as new hyperscale and colocation sites standardize on LFP.
