The global data center battery market is projected to expand from USD 4.82 billion in 2026 to USD 10.23 billion by 2032, according to a ResearchAndMarkets report, as operators invest in backup power and energy storage for enterprise, colocation and hyperscale facilities. The report says AI, cloud computing and high-performance computing are driving rapid capacity additions, increasing the need for batteries in UPS (uninterruptible power supply) systems and BESS (battery energy storage systems). Advanced lead-acid batteries are expected to retain a significant share because of their installed base, lower upfront cost and compatibility with existing infrastructure, while colocation data centers are forecast to post strong growth as enterprises outsource IT infrastructure. North America is identified as a key growth region through 2032, supported by hyperscale, AI and cloud infrastructure investment.
