1. Reliable Deep‑Discharge & Tripping Performance Strong deep‑discharge resistance and fast recovery capability ensure stable instant power output for switch tripping and protection actions under sudden power‑loss conditions, securing power system safety.

2. Excellent Environmental Adaptability for Power Rooms Stable operation within −20℃~50℃ with low self‑discharge. Perfectly suited for cabinet‑mounted installation in power distribution rooms, transformer stations and unattended power‑supply stations.

3. Safe Sealed Design with Zero Maintenance Leak‑proof and acid‑fume‑free fully sealed construction requires no regular water replenishment. It avoids corrosion to switchgear and control circuits, complying with power‑industry safety standards.

4. High Compatibility & Steady Control Power Output Standard 12V voltage matches mainstream low‑voltage switch control modules, protection relays and distribution monitoring systems. Low internal resistance guarantees consistent power supply for long‑term standby and instantaneous tripping loads.

• Tripping & control backup power for low‑voltage switch cabinets and distribution panels
• Standby power for power‑system secondary control equipment, protection relays and monitoring devices
• Emergency power supply for transformer stations, box‑type substations and unattended distribution stations
• Backup energy for power distribution room monitoring systems and indicator lighting units

• Charging: Float charge: 13.5–13.8V; Equalizing charge: 14.4–14.8V. Avoid overcharging or undercharging.
• Discharging: Daily discharge depth ≤50%; complete full discharge is strictly prohibited to prevent permanent battery degradation.
• Environment: Install in well‑ventilated, dry and dust‑free cabinet spaces. Avoid direct sunlight and moisture. Operating temperature: −20~50℃, optimal working temperature: 20–25℃.
