Commercial service places especially harsh demands on batteries. Standard starting, deep cycle, and dual purpose batteries cannot maintain the power required by your engine and auxiliary equipment. The marine commercial battery offers the widest selection of sizes and types to fit your specific needs. Traditional methods of wiring batteries together in banks of two or more met power requirements. However, they were typically unable to withstand the pounding vibrations, harsh temperature extremes, and corrosive saltwater environments. Only our marine batteries are designed for this type of service, and can repeatedly stand up to this kind of abuse.
