Marine Battery Box – Plastic Waterproof Case (Large 200 x 410 x 200 mm)

The large plastic battery box (code 1982) is designed to accommodate the bigger batteries used in more powerful boats and electrical systems. With its increased volume and robustness, it provides a reliable solution for protecting high-value deep cycle or starting batteries – the “heart” of your onboard electrical setup.

Features and Benefits:

• More Space: With internal dimensions allowing for higher capacity batteries (typically up to around 120 Ah, corresponding to Group 27/31 marine batteries), this box is suitable for diesel engines, dual-battery banks, or heavy-duty electrical systems. The space can also be used to house two smaller 12V batteries combined (wired in series or parallel) in one enclosure if they physically fit.
• Reinforced Build: For heavier batteries, it’s crucial that the box maintains its shape and strength – this model has reinforced walls and bottom to support the weight and any jolts in rough seas. Even if installed in an engine room, the box withstands elevated temperatures and vibrations, protecting the battery inside.
• Built-in Handles: The lid features convenient molded handles that make it easier to carry the battery when it’s enclosed in the box. This is practical for seasonal battery removal for charging or repositioning. The handles being part of the lid eliminates the need to directly grip the heavy battery itself.
• Safety and Organization: In addition to isolating the battery from its surroundings, the box helps give a tidy look to the compartment. Cables can be routed neatly through the lid, reducing clutter. No more worries about a stray metal tool falling onto the terminals – everything is covered. Large boxes often have space to mount quick-connect external terminals or a battery disconnect switch on the lid, providing easy access to cut power without opening the box.
• Accessory Compatibility: This model adheres to the "CEE" standard for battery boxes, meaning many commercially available accessories (such as charge level indicators, external posts, vent caps) can be integrated. If your boat has a specific battery tray or hold-down designed for standard sizes, the 200x410x200 mm footprint matches one of the popular standards and should fit.

Usage: The large battery box is favored in medium to large vessels – from 5–6 meter cruisers to 8–10 meter yachts, where typically powerful engines and numerous electrical consumers (fridges, winches, nav systems, etc.) are present. It’s an excellent choice for sailboats as well, which often have multiple batteries (for starting, house service, sometimes bow thrusters) – with these boxes, all can be safely enclosed. In RVs and camper vans that use big deep-cycle batteries for camping, a similar box keeps the interior safe from fumes and allows secure storage under seats or in exterior compartments.

In summary, if you have a large battery or bank of batteries, this large plastic battery box gives you peace of mind that they are safeguarded. Its durable construction and thoughtful features make it a must-have for anyone looking to keep their boat’s electrical system shipshape and ensure safety for crew and equipment alike.
