II. Key Advantages

• Large 200Ah Capacity: Equipped with 200Ah high capacity, it provides extended standby duration, perfectly meeting the high-power demand of communication cabinets and their internal core equipment.
• Communication Cabinet Adaptive: Optimized overall size is tailored for standard communication cabinets, facilitating flexible layout, quick installation and seamless integration with cabinet equipment.
• Stable Backup Performance: Customized for communication cabinet scenarios, it delivers consistent power supply during sudden power outages, effectively avoiding interruptions to telecom services and equipment operation.
• Sealed & Maintenance-Free: Adopts a valve-regulated sealed structure combined with an AGM separator, realizing zero leakage, no need for regular maintenance, and safe operation in closed cabinet environments.
• Excellent Discharge Stability: Built with reinforced grids and thickened plates, it ensures steady high-current output and superior deep discharge recovery, providing reliable emergency power support.
• Harsh Environment Tolerance: Low self-discharge rate and wide operating temperature range enable stable work in indoor/outdoor communication cabinets and complex harsh conditions, reducing O&M costs effectively.

III. Typical Applications

1. Backup power for indoor and outdoor communication cabinets
2. DC standby power for communication cabinet core equipment and access network devices
3. UPS/EPS backup systems for communication cabinet projects
4. Backup power for integrated communication cabinets and underground communication nodes

IV. Installation & Maintenance Guidelines

• Installation: Install the battery with terminals facing outward, arrange in single or double rows in communication cabinets, reserve adequate heat dissipation gaps; conduct anti-oxidation treatment on terminals after installation to avoid poor contact.
• Maintenance: It is recommended to operate in floating charge mode at 25℃ (battery life will be halved for every 10℃ increase in ambient temperature); regularly check terminal condition and battery shell, and address abnormalities promptly.
