This Group 4D commercial battery box is rotationally molded from premium low-density polyethylene, delivering a tough impact-resistant enclosure for demanding RV applications. Rated to remain rigid in temperatures down to -40°C (−40°F), the vented design prevents acid vapour buildup whilst large cable entry ports accommodate thick power leads and safety terminals.

Four-corner fastening with captive lid keeps your battery secure during rough travel. Brass-inserted star knobs resist corrosion, and the acid-resistant plastic shrugs off diesel spills, road salt, and chemical exposure. UV-stabilized for years of outdoor storage. Straightforward installation suits any RV electrical bay.
