SL12-65

Series Introduction：

The SL series is designed for frequent cyclic charge and dischargeapplications under extreme environments. By combining the newlydeveloped Nano Gel electrolyte with high density paste, the Solarrange offers high recharge efficiency at very low charge current. Theacid stratification is highly reduced by adding Nano Gel. This series is suited for energy storage for renewable energies such as PV, wing turbine power systems and CATV.

Technical Characteristics：

It has good small-current deep-cycle discharge performance and a long charging life;

Strong overcharge resistance;

Rapid recovery of over-discharged capacity;

Unique buried lead wires for convenient installation;

Wide operating temperature range from -40℃ to 60℃ ,

suitable for various outdoor environments;

Unique sealing valve structure design adapts to highaltitude(up to 4500m) areas;

Sealed reaction efficiency ≥ 99%, no need to add water, achieving true maintenance-free operation.
