12V 150AH Valve Regulated Sealed Lead Acid Battery For Airport Navigation Tower

I. Core Parameters

• Rated Voltage: 12V
• Rated Capacity: 150Ah (C20 rate)
• Dimensions (L×W×H): 481×170×242mm
• Charging Voltage: Float 13.6–13.8V; Cycle 14.4–14.8V
• Self-discharge Rate: ≤2%/month (25℃)
• Operating Temperature: -20℃～50℃
• Design Life: >10 years (float charge at 25℃)

II. Key Advantages

• High Capacity & Reliable Standby: The 150Ah large capacity delivers extended standby time, precisely meeting the continuous power demand of railroad signal equipment and airport navigation tower systems, ensuring seamless power supply even during prolonged power outages critical to transportation safety.
• Dual-scenario Customization: Specifically designed for railroad signal and airport navigation tower scenarios, it perfectly adapts to the power characteristics of precision signal transmitters and navigation equipment, providing stable backup support to avoid safety risks caused by power interruptions.
• Sealed & Maintenance-free Operation: Adopting a valve-regulated sealed structure with an AGM separator, it achieves zero leakage and no acid mist, eliminating the need for regular maintenance and ensuring safe operation in both indoor equipment rooms and outdoor auxiliary facilities of navigation towers and railroad signal stations.
• Superior Discharge Stability: Equipped with reinforced whisker-enhanced composite plates, it ensures stable high-current output (35C5 instantaneous discharge without damage) and excellent deep discharge recovery, reliably meeting the emergency power needs of high-precision railroad signal and airport navigation equipment.
• Strong Environmental Resilience: With an ultra-wide operating temperature range and low self-discharge rate, it can work stably in harsh outdoor environments such as high-altitude airport navigation towers and open-air railroad signal nodes, adapting to extreme temperature changes and reducing operation and maintenance costs significantly.

III. Typical Applications

• Backup power for railroad signal transmitters, switch machines and unattended railroad signal nodes, ensuring accurate signal transmission for railway operation safety.
• Standby power for airport navigation tower equipment, including navigation lights, communication transmitters and precision navigation control systems, safeguarding flight takeoff and landing safety.
• DC backup power for railroad signal control systems and medium-sized UPS/EPS systems in airport navigation infrastructure projects, meeting the high-reliability power demand of critical transportation facilities.

IV. Installation & Maintenance Guidelines

• Installation: Mount with terminals facing outward, arrange in single or double rows in standard equipment cabinets, reserve sufficient heat dissipation gaps; use copper bar laser welding for multi-group series connection (voltage drop ≤0.04V); conduct anti-oxidation treatment on terminals after installation to ensure stable connection and avoid signal interference.
• Maintenance: It is recommended to operate in float charge mode at 25℃ (battery life will be halved for every 10℃ increase in ambient temperature); enable stepped preheating for low-temperature charging (current not exceeding 37.5A); regularly inspect terminal tightness, battery appearance and internal parameters, and handle abnormalities promptly to ensure equipment safety.
