Centralized Emergency Light Battery 12V 24AH For Modern Building Safety Infrastructure

I. Core Product Parameters

• Nominal Voltage & Capacity: 12V / 24Ah (20HR rate), fully compatible with centralized emergency lighting controllers, distribution boxes, and auxiliary power modules.
• Discharge Characteristics: 20-hour rate ≥24Ah; 1-hour rate ≥16.1Ah; ensuring reliable illumination for 60–90 minutes under typical emergency lighting loads.
• Internal Resistance: Internal resistance ≤12mΩ when fully charged; self-discharge rate ≤2.5% per month at 20°C,  making it ideal for low-maintenance commercial and residential buildings.
• Charge Parameters: Recommended float voltage: 13.62–13.80V; equalization voltage: 14.1–14.4V; Built-in overcharge protection ensures safe compatibility with standard emergency lighting system chargers.

II. Core Technical Advantages

• High Reliability for Life Safety Applications
  Manufactured with valve-regulated, sealed lead-acid technology and a flame-retardant ABS casing (UL94 V-0 rated). Double-layer leak-proof seals provide enhanced safety, meeting stringent building code requirements for emergency lighting power sources.
• Wide Temperature Tolerance for Variable Installation Environments
  Operates reliably across a temperature range of -20°C to +50°C, maintaining ≥90% of rated capacity under extreme conditions. Its resistance to temperature variation eliminates the need for climate-controlled battery rooms, allowing flexible placement in electrical closets, basements, or parking garages.
• Extended Float Life & True Maintenance-Free Design
  Utilizing optimized grid alloys and advanced paste formulations, this battery achieves a float service life of 6–8 years in standby mode and supports ≥300 charge-discharge cycles. The AGM separator technology ensures no water or acid refills are ever required, significantly reducing ongoing maintenance costs.
• Seamless Integration with Centralized Systems
  Easily integrates with most centralized emergency lighting panels, self-test systems, and building automation platforms. Standard terminal configurations and compact dimensions allow direct drop-in replacement for common models such as GP24-12, simplifying upgrades and field service.

III. Application Scenarios 

1. Centralized Emergency Lighting Systems: Serves as the primary backup power source for centralized inverters and distribution units powering exit signs, emergency luminaires, and stairwell lighting.
2. EPS (Emergency Power Supply) Systems: Primary backup power for emergency lighting, fire pumps, smoke exhaust fans, and other critical fire safety loads.
3. Emergency Lighting & Voice Evacuation Systems: Ensures illumination and voice guidance during fire.
4. Fire Suppression Control Systems: Supports gas or water suppression controls in server rooms and industrial plants.
5. Unattended Substations & Pump Rooms: Long-term maintenance-free operation with automatic backup upon mains failure.

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.
