Watertight Battery Box up to 100Ah with Ventilation (ISO 10133)

This watertight battery box provides maximum protection for your battery in marine environments. Designed in accordance with ISO 10133 standards, it ensures safe onboard use by keeping water out and venting any gases released by the battery. The rugged polypropylene shell resists damage from battery acid and harsh weather. It features a secure lid with an integrated vent, allowing hydrogen gas to escape and not build up inside. This reduces corrosion risk and boosts safety during charging and operation.

In addition to being waterproof, the box also shields surrounding areas from possible acid spills. With internal dimensions accommodating batteries up to 100Ah, it suits a wide range of applications – from starting batteries for outboard engines to deep-cycle batteries for onboard electronics. The package includes a strong tie-down strap and stainless brackets that keep the box and battery firmly in place even in rough seas or heavy vibrations. Large molded handles make it easy to carry or reposition the box, and its universal design allows installation in various locations – in the bilge, under a bench, or on deck.

• Recommended use: Perfect for small and medium-sized vessels (e.g., fishing boats, runabouts up to ~20 ft) where the battery needs protection from spray, rain, and moisture.
• Great for camping too: Can be used in RVs or off-grid solar setups – its waterproof, vented design makes it ideal for safely housing a battery outdoors.
• Safety & standards: By meeting ISO 10133 for small craft, the box adheres to marine electrical safety requirements. This gives you peace of mind – the battery is secured against short circuits, spills, and gas buildup.
• Extend battery life: Keeping your battery dry, ventilated, and secure helps prolong its life and maintain optimal performance of your connected equipment (navigation systems, lights, trolling motor, etc.).
