Noco HM462

Dual L16 Commercial-Grade Battery Box - Heavy-Duty 12 V Enclosure for Two 6-Volt Batteries

The NOCO HM462 is a rugged, marine-grade battery box designed to securely house two Group L16 or equivalent6 V batteries. Ideal for off-grid solar, marine, RV, trailer, generator, and industrial power systems, it delivers robust protection and compliance for critical battery installations.

Features

Built from premium rotationally molded polymer, the HM462 withstands harsh environments×withstanding extreme cold, prolonged UV exposure, and chemical exposure without degradation Its captive lid with four fastening knobs secures the enclosure firmly, while vents.

Advanced Options

promote safe off-gassing of hydrogen. The sizable internal reservoir safeguards surrounding components from potential acid leakage Large cable entry ports accommodate up to 4/0 AWG wiring, supporting high-current applications. Its USCG and ABYC certifications mean it's safe for use aboard boats, yachts, generators, and mobile equipment

Product Key Features

• Commercial-Grade Construction: Heavy-duty rotationally molded, UV, impact, oil, gas, and acid-resistant×durable to -20 °FSecure Lid System: Four-corner fastening with captive lid×stays attached and secure

• Full-Flow Ventilation: Integrated vents safely allow gas dissipation

• Acid Leak Containment: Large internal reservoir protects against corrosion

• Marine-Certified: Compliant with USCG 183.420 & ABYC E-10.7 requirements
