Performance Features
- Safe and Reliable: Adopts a highly reliable double-sealed pole structure with excellent impact resistance and sealing performance, ensuring no electrolyte leakage¹. Equipped with a domestic explosion-proof acid-filtering plate safety valve with proper opening and closing pressure, featuring explosion-proof and acid mist filtration functions. It can release excess gas during overcharging to prevent battery expansion and cracking, as well as acid mist escape¹.
- Excellent Performance: Uses pure raw materials and additives, and specially formulated electrolyte, resulting in low internal resistance, good high-rate characteristics, and strong charge acceptance¹. The electrolyte is made of American fumed silica, presenting a gel state in the finished battery that does not flow, with no leakage or electrolyte stratification¹. The battery has a large heat capacity, reducing the risk of thermal runaway, is not easy to dry out, and can be used in harsh environments³.
- Resistant to Multiple Working Conditions: Excellent vibration resistance: After a fully charged battery is fixed, it vibrates for 1 hour with an amplitude of 4mm and a frequency of 16.7Hz, with no leakage, battery expansion or cracking, and normal open-circuit voltage². Excellent impact resistance: A fully charged battery is naturally dropped from a height of 20cm onto a 1cm-thick hard wooden board 3 times, with no leakage, battery expansion or cracking, and normal open-circuit voltage². Excellent over-discharge resistance: A fully charged battery is discharged at a constant resistance for 3 weeks at 25℃, with a recovery capacity of over 75%². Excellent charge resistance: A fully charged battery is charged at 0.1C₁₀ for 48 hours at 25℃, with no leakage, battery expansion or cracking, normal open-circuit voltage, and a capacity retention rate of over 95%².
Application Fields³
- Communication Systems: Such as communication base stations, switching rooms, etc., providing reliable backup power for communication equipment.
- Power Systems: Suitable for substation DC screens, relay protection devices, etc., ensuring the stable operation of power systems.
- Emergency Lighting Systems: Provides power for emergency lights in emergencies to ensure lighting.
- Automation Control Systems: Provides stable backup power for automation equipment.
- Fire Protection and Safety Alarm Systems: Ensures the normal operation of related equipment in emergencies such as fires.
- Solar and Wind Energy Systems: Serves as an energy storage unit to store excess electric energy and improve energy efficiency.
- Other Fields: Also used in computer backup power supplies, portable instruments, medical system equipment, etc.
