I. Core Parameters

• Rated Voltage: 12V
• Rated Capacity: 38Ah (C10 rate, 1.80V per cell)
• Dimensions (L×W×H): 198×167×173mm
• Charging Voltage: Float 13.6–13.8V; Cycle 14.4–14.8V
• Self-discharge Rate: ≤2%/month (25℃), suitable for long-term standby in unattended sites
• Operating Temperature: Discharge -20℃～50℃
• Design Life: 10 years (float charge at 25℃)

II. Key Advantages

• Compact & Space-saving: Optimized small size fits the narrow installation space of telecom towers and signal transmission cabinets, facilitating flexible layout and quick installation.
• Dual-scenario Adaptation: Customized for telecom towers and broadcasting signal transmission, precisely matching the power demand of related equipment, ensuring stable backup during sudden power outages.
• Sealed & Maintenance-free: Adopts valve-regulated sealed structure with AGM separator, no leakage, no regular maintenance, suitable for long-term outdoor and unattended operation.
• Stable Discharge Performance: Reinforced grid design ensures steady high-current output and good deep discharge recovery, reliably supporting emergency power needs of signal transmission equipment.
• Strong Environmental Tolerance: Wide operating temperature range and low self-discharge rate, adapting to harsh outdoor weather conditions of telecom towers and signal relay stations, reducing O&M costs.

III. Typical Applications

• Backup power for telecom tower base station auxiliary equipment and unattended tower nodes.
• Standby power for broadcasting signal transmitters, relay stations and outdoor signal transmission cabinets.
• DC backup power for outdoor signal transmission 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 sufficient heat dissipation gaps; conduct anti-oxidation treatment on terminals after installation to ensure stable connection.
• Maintenance: Recommend float charge operation at 25℃ (battery life halves for every 10℃ temperature rise); regularly inspect terminal tightness and battery appearance, handle abnormalities promptly.
