I. Core Parameters

• Rated Voltage: 12V
• Rated Capacity: 18Ah (C20 rate)
• Dimensions (L×W×H): 182×77×167mm
• Charging Voltage: Float 13.6–13.8V; Cycle 14.4–14.8V
• Self-discharge Rate: ≤2%/month (25℃)
• Operating Temperature: Discharge -20℃～50℃
• Design Life: 5 years (float charge at 25℃)

II. Key Advantages

• Compact & Space-saving: Its optimized small size is perfectly suited for the limited installation space of telecom towers and fiber optic network cabinets, allowing for flexible placement and swift deployment.
• Dual-scenario Adaptability: Custom-designed for both telecom towers and broadband fiber optic networks, it precisely meets the power needs of related equipment and ensures stable backup during unexpected power outages.
• Sealed & Maintenance-free: Adopting a valve-regulated sealed structure with an AGM separator, it achieves zero leakage and requires no regular maintenance, making it suitable for long-term outdoor and unattended operation.
• Reliable Discharge Performance: The reinforced grid structure ensures stable high-current output and excellent deep discharge recovery, reliably fulfilling the emergency power requirements of fiber optic network transmission equipment.
• Strong Environmental Resilience: With a wide operating temperature range and low self-discharge rate, it can adapt to the harsh outdoor weather conditions of telecom towers and fiber optic network nodes, reducing operation and maintenance costs.

III. Typical Applications

• Backup power for auxiliary equipment of telecom tower base stations and unattended tower nodes.
• Standby power for fiber optic signal transmitters, distribution cabinets and outdoor fiber optic network nodes.
• DC backup power for fiber optic network peripheral devices and small UPS/EPS systems in related projects.

IV. Installation & Maintenance Tips

• Installation: Mount with terminals facing outward, arrange in single rows in narrow cabinets, reserve adequate heat dissipation gaps; perform anti-oxidation treatment on terminals after installation to ensure a stable connection.
• Maintenance: It is recommended to operate in float charge mode at 25℃ (battery life will be halved for every 10℃ increase in ambient temperature); regularly check terminal tightness and battery appearance, and handle abnormalities in a timely manner.
