GEL Deep Cycle · Series RDG

RDG Series – Deep Gel

Deep cycling with full recovery from deep discharge.

The RDG Series is the ultimate 'all-terrain' battery, combining deep cycle endurance with the thermal resilience of gelled electrolyte (Nano-silica Gel). Classified by EUROBAT as 'High Performance', this series offers a 12-year design life, standing out for its ability to operate in extreme temperature environments and constant vibrations without the risk of thermal runaway. Its advanced engineering allows for total recovery after severe deep discharges, making it the most powerful commercial choice for off-grid renewable energy installations, marine use, and industrial environments where reliability is critical and maintenance must be non-existent.
