12V 55AH Traffic Signal Battery / Railway Signaling Control Battery

I. Core Product Parameters

• Rated Parameters: 12V 55AH, compatible with signal power screens and UPS without the need for additional voltage regulation.
• Discharge Performance: 10-hour discharge rate ≥52Ah, 1-hour discharge rate ≥46Ah, capable of providing continuous power for 1-2 hours during grid power interruptions.
• Internal Resistance and Self-discharge: Full-charge internal resistance ≤8mΩ, monthly self-discharge ≤3% at 25℃, ideal for unattended operation.
• Charging Parameters: Float charging voltage 13.38-13.62V, equalizing charging voltage 14.1-14.40V, with automatic charge conversion and overcharge protection functions.

II. Core Technical Advantages

• High Reliability: Adopts valve-regulated sealed lead-acid technology, featuring double anti-leakage sealing and a flame-retardant casing, which meets the safety standards of railway equipment rooms.
• Wide Temperature Adaptability: Operates stably at -15℃~50℃ (with capacity output ≥92%), resists vibration and impact, and requires no additional temperature control under complex working conditions.
• Long Service Life & Maintenance-free: Equipped with optimized plate technology (8-10 years of float charge life, cycle life ≥350 times) and AGM separators, it requires no water or acid replenishment, making it suitable for unattended use.
• Intelligent Adaptation: Integrated with BMS for real-time monitoring, it is compatible with railway signal monitoring systems; clear pole markers and adaptive dimensions enable easy installation.
