NOCO HM484 8D Group Marine Battery Box, Black
NOCO HM484 8D Group Marine Battery Box, Black — Product description
The NOCO HM484 is a heavy-duty marine battery box sized for a single 8D group battery. Molded from tough polyethylene, it shrugs off impacts down to -40 degrees Fahrenheit and keeps your big house or starting battery secure, ventilated, and protected from the elements.
If you're running a big 8D battery on your boat, you need a box that can actually hold it. The NOCO HM484 is sized specifically for 8D group batteries, the tall, heavy ones that power larger house banks and diesel starting duty. It's molded from thick polyethylene plastic, so it won't crack, corrode, or rattle apart when the water gets rough.
The full-flow ventilation matters more than folks think. Batteries off-gas, and that gas needs somewhere to go. This box vents it out so nothing builds up in an enclosed compartment. The captive lid stays put, and the large cable entry holes give you room to route heavy-gauge cable without pinching or chafing.
Black finish, impact resistant down to -40 degrees Fahrenheit, and simple to strap down. It's a straightforward, honest piece of gear that does one job and does it well. Rig it up and forget about it.
