Before purchasing, confirm your batteries fit within the internal dimensions to ensure safe, reliable installation.

How much battery space does the enclosure provide?

The interior is sized to accept two standard 12V batteries within its stated limits. Measure your battery length, width and height against the internal dimensions to confirm a fit; this box is not compatible with oversized 4D/8D or extra-wide batteries.

• Internal: 21.7" L × 8" W × 11" H — fits most dual 12V setups
• External footprint: 22.6" L × 9" W × 12.2" H — allows space for mounting
• Not for batteries wider than 8" (203 mm) or taller than 11" (279 mm)

What protective features prevent water, corrosion, and heat damage?

The box is built from premium stainless steel with a black anti-rust finish that resists salt and humidity. Its recessed, sealed top cover limits water ingress and helps shield terminals from moisture and debris without obstructing ventilation when installed correctly.

• Stainless steel shell for long-term corrosion resistance
• Waterproof top cover with recessed base to keep water away
