Large sealed lead-acid batteries (usually referred to as "large sealed valve-controlled lead-acid batteries" or "high capacity lead-acid batteries") are widely used in applications requiring large capacity, stable discharge and durability due to their design characteristics. The following are the main uses and features:
1. Communications
-Base station backup power supply: provides backup power for mobile communication base stations and optical cable repeater stations to ensure the normal operation of communication equipment in case of power failure.
-Data center: Supports UPS (uninterruptible power supply) system to prevent servers and network equipment from being interrupted by power failure.
2. Power system
-Substation/distribution system: as a DC operating power supply, it provides power for relay protection, automatic devices and circuit breakers.
-Grid energy storage: short-term energy storage for peak load filling or renewable energy (such as wind power, photovoltaic).
3. Transport
-Railway and rail transit: power supply for signaling systems, locomotive start-up and emergency equipment in carriages.
-Ship and port equipment: used for auxiliary power of ships, shore power systems or port lifting machinery.
4. New energy storage
-Solar/wind energy storage: Storage of unstable power generation for use at night or when there is no wind. Common in off-grid or hybrid energy systems.
-Home energy storage system: in conjunction with photovoltaic, to provide emergency power for the home.
5. Industrial applications
-Forklift/electric handling equipment: as a power battery, suitable for high load, frequent charge and discharge conditions.
-Mining equipment: provides power for underground lighting, motor cars, etc., and explosion-proof models can be used in dangerous environments.
6. Emergency and safety systems
-Fire/fault lighting: emergency power supply for hospitals, shopping malls and other places.
-Security system: backup power supply for monitoring and alarm equipment.
7. Other areas
Medical equipment: such as backup power supply for hospital ICU and operating room.
Military use: radar, field communication equipment, etc.
The core advantage of large lead acid battery
High capacity: suitable for large current discharge, strong endurance.
Sealed maintenance free: the electrolyte is fixed, there is no risk of leakage, and no need to add water frequently.
Low cost: compared with lithium battery, the initial investment is lower and the technology is mature.
Temperature adaptability: stable performance in the range of-20℃~60℃.
