12V 55AH Modern Data Center Battery IT Cabinet Backup Battery

I. Core Product Parameters

• Nominal Voltage & Capacity: 12V / 55Ah (10HR rate), fully compatible with rack-mounted UPS units, DC backup systems, network switches, and auxiliary power modules inside IT cabinets.
• Discharge Characteristics: 10-hour rate ≥55Ah; 1-hour rate ≥36.9Ah; supporting backup durations of 30 to 90 minutes under typical IT cabinet loads (e.g., servers, switches, and patch panels).
• Internal Resistance: Internal resistance ≤10mΩ when fully charged; self-discharge rate ≤2.5% per month at 20°C, making it well-suited for low-maintenance data center deployments.
• Charge Parameters: Recommended float voltage: 13.62–13.80V; equalization voltage: 14.1–14.4V; built-in overcharge tolerance ensures safe operation with standard cabinet-level UPS and DC power supplies.

II. Core Technical Advantages

1. Enhanced Reliability for Critical IT Infrastructure
   Engineered with valve-regulated, sealed lead-acid technology, this battery features a flame-retardant ABS casing (UL94 V-0 rated) and double-layer leak-proof seals. These design choices meet stringent data center fire safety standards and provide robust protection for densely packed IT cabinets.
2. Broad Temperature Tolerance for Variable Rack Environments
   Operational across a wide temperature range of -20°C to +50°C, the battery maintains ≥90% of its rated capacity even under thermal stress. Its resistance to vibration and shock reduces the need for strict temperature control within individual cabinets, offering flexibility for edge nodes and telecom rooms.
3. Extended Service Life and Truly Maintenance-Free Design
   Thanks to an optimized grid alloy and advanced paste formulation, this battery achieves a float service life of 6–8 years in standby mode and supports over 300 charge-discharge cycles. The AGM separator technology eliminates any requirement for water or acid refills, drastically lowering operational overhead for facility managers.
4. Seamless Compatibility with Existing Cabinet Infrastructure
   The battery integrates effortlessly with most rack-mounted UPS platforms, DC backup units, power distribution equipment, and cabinet-level EPS systems. Its standard terminal configuration and compact dimensions allow direct one-to-one replacement of popular models such as the GP55-12, simplifying field upgrades and maintenance.

III. Application Scenarios 

• Rack-Mounted UPS Protection: Serves as the primary energy storage unit for UPS systems installed inside IT cabinets, safeguarding network switches, routers, and access-layer servers.
• Edge Computing Nodes: Provides reliable backup power for space-constrained micro data centers and remote edge locations where uptime is mission-critical.
• Telecom and Network Racks: Supports DC power architectures in telecommunications rooms and interconnect points within large data center campuses.
• Access Control and Security Systems: Powers biometric readers, electronic locks, and surveillance equipment in colocation and enterprise data center facilities.
• Unattended Server Halls and Remote Cabinets: Enables automatic, maintenance-free backup during mains interruptions—ideal for high-density or remotely located IT enclosures.

IV. Quality Assurance and Compliance

• Compliance Standards: Strictly conforms to IEC 60896-21/22, GB/T 19638, and UL 1989 (fire alarm system battery standard), fully meeting fire regulatory requirements.
• Quality Inspection: Full production process follows ISO 9001 and ISO 14001 standards, with 100% final voltage, capacity, and leak testing to ensure consistent performance.
• After-sales Support: Comprehensive warranty (typically 12 months) with technical support, failure analysis, and replacement service to ensure long-term system readiness.
