The Concorde RG-400E/13 is a valve regulated lead acid (VRLA) absorbed glass mat (AGM) main battery used for starting and backup of DC power bus systems. RG-400E/13 is a direct replacement in form, fit and function for an equivalent nickel cadmium model. RG Series batteries are the original AGM battery designed for the U.S. military. Replenishment of water or electrolyte is never required, providing maintenance-free operation in a nonspillable design that operates upright, on its side or end. RG-400E/13 delivers reliable power and long life and improves aircraft readiness. RG Series batteries are pre-tested and fully charged in the factory, ship Hazmat Exempt and are ready to install. Concorde batteries are certified for installation on more than 1,000 aircraft models through Type Certification, 62 STCs and multiple PMAs. Concorde has more than 90 VRLA model part numbers.
