The small and medium series lead-acid batteries are two common types of valve-controlled sealed lead-acid batteries (VRLA), which are classified according to the size, capacity and application scenarios of the battery. They have a wide range of applications in various fields, as follows:
The use of small lead-acid batteries (small sealed batteries) is usually small in capacity (generally less than 120Ah), compact in structure, and suitable for scenarios requiring high power density and portability. It mainly includes:
1. Communication systems
-Used for base station, switch, optical fiber communication equipment and other backup power supply to ensure the normal operation of equipment when power is cut off.
2. Emergency lighting system
-For example, fire emergency lights and safety exit indicator lights provide continuous power in emergency situations.
3. Uninterruptible Power Supply (UPS)
-Power supply for critical equipment such as computer servers, data centers and medical equipment.
4. Security and monitoring system
-Provide backup power for surveillance cameras, alarm systems, access control systems, etc.
5. Portable electronic devices
-Such as power tools, measuring instruments, medical equipment, etc.
6. Solar and wind energy storage
-For small off-grid energy storage systems, such as solar street lights and small household energy storage devices.
The use of medium and dense series lead acid batteries
Medium sealed batteries (medium sealed batteries) have large capacity (usually 100Ah~300Ah) and are suitable for higher power applications, including:
1. Backup power supply for the power system
-DC power supply system for substations, distribution rooms and other places to ensure the stable operation of power equipment.
2. Large UPS system
-Suitable for enterprise server rooms, financial data centers and other scenarios that require long-term backup power.
3. Industrial automation control
-Provide stable power for PLC, industrial robot and automation production line.
4. Railway and air signal systems
-Used for critical infrastructure such as railway signal lights and aviation navigation equipment.
5. Energy storage and new energy systems
-Suitable for medium-sized solar energy storage, wind energy storage and microgrid systems.
6. Electric vehicles and special equipment
-Used for electric forklifts, golf carts, AGV (Automatic guided vehicles), etc.
Comparison of main features
| Characteristics | Small series | Medium series |
| Capacity range | usually ≤120Ah | 100Ah~300Ah |
| Application scenarios | Portable devices, small UPS | Industrial UPS, energy storage systems |
| Structural characteristics | Compact, lightweight | Larger volume, higher power |
Sum up
The small series is suitable for small, portable devices, while the medium series is more suitable for industrial grade, large capacity energy storage and power systems. Both are valve-controlled sealed design, maintenance free, leak-proof, suitable for scenarios with high requirements for safety and stability.
