1. Innovative Gel Electrolyte, Extended Cycle Durability

   Adopts silica‑gel immobilized electrolyte to avoid acid stratification and leakage risks. Deep‑discharge cycle performance is improved by 50% versus conventional lead‑acid batteries, perfectly coping with frequent charge‑discharge cycles of large‑scale solar storage systems.

2. Ultra‑Wide Temperature Adaptability & Strong Ruggedness

   Functions stably under ‑40℃~65℃ working temperature, with outstanding resistance to extreme climates and vibration. Suited for large outdoor photovoltaic stations and remote off‑grid power projects with harsh environmental conditions.

3. Sealed Maintenance‑Free Structure, Low Lifecycle Costs

   Valve‑regulated fully sealed design eliminates water replenishment throughout its service life. Ultra‑low self‑discharge rate retains residual power during long‑term standby, cutting maintenance burdens for isolated off‑grid sites.

4. Large‑Capacity Stable High‑Load Output

   High‑capacity configuration and low internal resistance reduce voltage drop under heavy‑load discharge. It guarantees continuous stable operation of solar inverters and electrical loads, meeting long‑duration power supply requirements of large off‑grid energy storage systems.

5. Enhanced Safety with Flame‑Retardant & Anti‑Corrosion Design

   Zero acid leakage risk. Flame‑retardant casing and integrated multi‑protection circuits strengthen outdoor operational safety, effectively preventing fire hazards and chemical corrosion risks.
