Server rack batteries are available through specialized online retailers and major e-commerce platforms. Amazon offers multiple options like the CyberPower CP1500PFCRM2U UPS system with 1500VA/1000W capacity in a 2U rackmount design. For enterprise-grade solutions, consider APC, Eaton, or Tripp Lite’s official websites, which provide compatibility filters for server racks. Industrial suppliers like CDW and B&H Photo Video also stock lithium-ion and VRLA rack batteries with detailed spec sheets. Pro Tip: Verify rack unit (RU) dimensions and terminal types before purchasing—mismatched sizes or connectors cause installation failures.

What defines a server rack battery?
Server rack batteries are standardized power modules designed for vertical mounting in data center racks. They prioritize compact 2U/3U form factors and hot-swappable designs for uninterrupted power supply (UPS) during outages. Key metrics include voltage (48V/72V DC), capacity (1–10kWh), and compatibility with major rack widths (19″/23″).
These batteries use lithium-ion or sealed lead-acid (SLA) chemistries, balancing energy density and fire safety. For instance, a 3U 72V LiFePO4 battery typically delivers 5kWh with a 10-year lifespan. Pro Tip: Prioritize UL 1973-certified models for data centers—non-compliant units risk thermal events in confined racks. Transitionally, while lithium dominates new installations, SLA remains cost-effective for low-cycle applications.
Where can I find enterprise-grade rack batteries?
Enterprise solutions are sold through authorized distributors like TechSoup and CDW, which offer volume discounts and SLA-backed warranties. Eaton’s 9PX 6kVA UPS and APC Smart-UPS Ultra 5kVA are industry standards. Practically speaking, CDW’s portal allows filtering by rack unit height, runtime, and communication protocols (SNMP/Modbus).
| Vendor | Key Product | Runtime at 50% Load |
|---|---|---|
| APC | SURT19200XLIC | 15–30 minutes |
| Eaton | 9PX6KiB | 20–45 minutes |
Transitionally, beyond runtime, consider scalability. Modular systems like Vertiv’s Liebert EXM permit incremental capacity upgrades. Did you know a 42U rack can house 14x 3U batteries delivering 70kWh? Pro Tip: Deploy dual-bus power distribution—single-bus setups create SPOFs (single points of failure).

FAQs
No—mounting rails, terminal types, and communication protocols vary. Always cross-check OEM compatibility matrices before purchasing.
How often should rack batteries be replaced?
Lithium-ion: 8–12 years; VRLA: 3–5 years. Annual impedance testing identifies capacity fade exceeding 20%—replace immediately if detected.
