II. Key Advantages

• Front Terminal Structure: Front-mounted terminals facilitate quick installation, daily inspection and routine maintenance, perfectly adapting to the layout of standard telecom cabinets; equipped with a portable handle for easy transportation.
• Optimal Capacity for Telecom Scenarios: 125Ah moderate large capacity balances standby duration and cabinet space, precisely matching the power demand of communication infrastructure and telecom equipment.
• Stable & Reliable Performance: Customized for communication infrastructure, it ensures stable backup power supply during sudden power failures, avoiding interruptions to telecom services.
• Sealed & Maintenance-Free: Adopts valve-regulated sealed design with AGM separator, achieving no leakage, no need for regular upkeep, and safe operation in closed telecom cabinet environments.
• Superior Discharge Stability: Reinforced grid and thickened plates enable stable high-current output and excellent deep discharge recovery, ensuring reliable emergency power support.
• Wide Environmental Adaptability: Low self-discharge rate and broad operating temperature range allow stable work in outdoor telecom nodes and harsh environments, lowering O&M costs.

III. Typical Applications

1. Backup power for communication infrastructure and standard telecom cabinets
2. DC standby power for telecom access network equipment and core communication nodes
3. UPS/EPS backup systems for communication infrastructure projects
4. Backup power for outdoor telecom cabinets and underground pipe gallery communication facilities

IV. Installation & Maintenance Guidelines

• Installation: Install the battery with front terminals facing outward, arrange in single or double rows in telecom cabinets, reserve adequate heat dissipation gaps; perform anti-oxidation treatment on terminals after installation to prevent poor contact.
• Maintenance: Recommend floating charge operation at 25℃ (battery life will be halved for every 10℃ increase in ambient temperature); regularly inspect terminal condition and battery shell, and address abnormalities in a timely manner.
