12V 120AH Sealed VRLA Gel Deep Cycle Marine Battery with M8 Copper Terminals - 12 Year Design Life, 38kg Weight
Professional-grade sealed gel battery designed for demanding marine and renewable energy applications with exceptional cycle life and performance.
The storage series is engineered for frequent cyclic charge and discharge operations in extreme environmental conditions. By integrating advanced Nano Gel electrolyte with high-density paste technology, this solar range delivers superior recharge efficiency even at minimal charge currents, while significantly reducing acid stratification.
Thick high-tin, low-calcium grid with high-density paste formulation
Over-designed capacity to prevent sulfation during low state-of-charge conditions
Advanced AGM separator technology
Dilute high-purity sulfuric acid enhanced with nano gel
Durable ABS construction
Factory-tested two-layer epoxy resin seal for maximum reliability
Integrated flame arrestor for enhanced safety
