FAA Approves STC to Replace Nickel-cadmium Main and Auxiliary Batteries
West Covina, CA - Concorde announces the selection of its RG-380E/60L as the original equipment battery for Viking Air Limited new production DHC-6-400 aircraft. Concorde also announces FAA approval of STC SA03971AT to replace nickel-cadmium main and auxiliary batteries on DHC-6-1, DHC-6-100, DHC-6-200, and DHC-6-300 vintage aircraft.
The STC provides for the replacement of the heavy-duty main 40Ah nickel-cadmium or AN-3150 lead-acid battery and/or the nickel-cadmium auxiliary battery. The main battery can be replaced with either of Concorde’s RG-380E/44 (42Ah) or higher capacity RG-380E/60L (48Ah) battery for cold weather operations. If the aircraft has not been modified for removal of the auxiliary battery, the original nickel-cadmium auxiliary battery can be replaced with the new RG-300 (3.3Ah).
RG-380E/44, RG-380E/60L and RG-300 are all TSO authorized and, as such, have passed rigorous TSO-C173 testing for duty cycle, electrical performance, temperature extremes, shock/vibration and environmental requirements. They also feature Concorde’s valve-regulated lead acid (VRLA) recombinant gas (RG) absorbed glass mat (AGM) technology. Unique design features such as proprietary PolyGuard separators (an additional layer of protection against shorting, unique to Concorde) robust plate construction, and over-the-cell-wall intercell connections for reduced internal resistance.
The advantages of converting from nickel-cadmium to Concorde’s RG Series batteries include lower cost of acquisition, zero maintenance and reduced battery costs per flight hour. Concorde batteries do not require deep cycling to remove the “memory effects” seen in nickel-cadmium batteries, do not require water or electrolyte replenishment and have no risk of thermal runaway.
With the benefit of RG Series batteries shipping Hazmat Exempt, transportation is more cost effective regardless of whether shipping by land, sea or air.
