Core Performance Advantages

1. Sealed Safety Design

   • Valve-regulated fully sealed structure prevents electrolyte leakage, supports vertical, horizontal, and other installation methods (inversion prohibited).
   • Built-in pressure safety valve automatically balances internal air pressure, avoids overpressure risks, and reduces acid mist overflow.

2. Stable Discharge Capability

   • High-purity lead alloy plates with low internal resistance and strong conductivity support high-current discharge (e.g., instant startup needs) with a stable discharge voltage platform.
   • Low self-discharge rate of <3% per month (at 25°C), maintains charge during long-term storage, suitable for backup power scenarios.

3. Durability and Adaptability

   • Vibration and impact resistance: Passes professional working condition tests; performance remains normal after vibration and drop tests while charging.
   • Wide-temperature operation: Normal startup in low-temperature environments; stable performance in high-temperature environments through heat dissipation design.

4. Maintenance-Free Features

   • No need for regular fluid replenishment, reducing manual maintenance costs; supports remote monitoring of voltage, internal resistance, and other parameters for convenient health assessment.

Typical Application Scenarios

• Communication Support: Base station backup power, data center UPS systems, emergency power supply for communication rooms.
• Power Systems: Substation DC panels, power automation equipment, energy storage for relay protection devices.
• New Energy Storage: Energy storage for photovoltaic/wind power generation systems, smoothing grid fluctuations.
• Industrial and Safety: Factory automation control, emergency lighting, fire alarm systems, backup power for security systems.
• Special Fields: Railway signaling, marine equipment, medical instruments, and other scenarios requiring high power reliability.

Usage and Operation Recommendations

1. Installation Standards

   • Ensure consistent battery specifications during series/parallel connections; terminals must be securely connected and insulated.
   • Installation environment should be well-ventilated, away from heat sources, and kept dry and clean.

2. Charging Management

   • Equalization charging is recommended for initial use; regularly check if the voltage is within the standard range during float charging.
   • Adjust charging parameters with temperature changes: reduce float voltage in high-temperature environments; increase voltage or provide insulation in low-temperature environments.

3. Maintenance Key Points

   • Regularly visually inspect the battery appearance (for bulging or leakage) and terminal condition (for oxidation or looseness).
   • Fully charge before long-term storage; perform supplementary charging every 3-6 months; recommended storage temperature is 5°C to 25°C.
