A double walled battery box for two oversized 8D batteries

This extra roomy box is designed to house and protect two oversized 8D batteries. Seamless, heavy wall, premium grade molded polyethylene construction offers superior chemical and impact resistance, even at temperatures as low as -40°F. Full flow ventilation ensures adequate cooling and increases the life of your batteries.

Because DC electrical shorts are one of the primary causes of onboard fires, installing a battery box with a cover is critically important for safety. For example, if you drop a crescent wrench across the terminals of an uninsulated marine battery, a massive short will result that could cause a serious electrical fire. Having a secure cover adds greatly to the safety. Two bolts with wingnuts hold the top securely in place.

Due to the corrosive nature of the sulfuric acid used in marine batteries, it is important to protect the surrounding metals and fasteners from exposure. This is especially true for aluminum boats. An acid reservoir is molded into the bottom of the box to contain any accidental spills and protect your boat and its components. Designed to limit battery movement to 1" in any direction, these battery boxes are compliant with USCG and ABYC guidelines.
