Description

Group 24–31 Snap-Top Battery Box BG31 (HM318BKS) is a rugged, fully ventilated battery enclosure designed to safely house a single Group 24, 27, or 31 automotive, marine, or RV battery. Manufactured by NOCO, this heavy-duty battery box is built from reinforced, UV-resistant plastic and engineered for demanding environments where durability and safety are critical.

The snap-top lid uses locking tabs to secure the cover firmly to the base, while reinforced carrying handles help prevent cracking during transport or installation. An adjustable internal divider allows the box to accommodate multiple battery sizes while maintaining a secure fit.

Designed to maintain structural integrity down to -20°F, this battery box also resists UV exposure, oil, gas, and other contaminants. Certified to U.S. Coast Guard CFR 183.420 and ABYC E-10.7 standards, it is suitable for enclosed and mobile installations requiring compliant battery containment.
