Concorde has developed a heated battery to maximize battery performance in cold weather
In cold temperatures having the right batteries can make a difference. Cold temperatures increase the internal resistance which decreases a battery’s capacity and slows the battery’s ability to accept charge current. For years, operators in cold climates have made it a practice to endure the inconvenience of removing batteries from aircraft, transporting and storing them in a heated environment, then reinstalling prior to departure. Some also use external heater blankets that wrap around the battery and heat the outermost cells when the aircraft is parked. Although this solution increases capacity, in some cases the battery cells are not equally heated resulting in diminished capacity and disproportionate recharge across battery cells.
In order to maximize battery performance, Concorde has developed heated batteries in our most popular sizes to mitigate these problems. Concorde’s RG-380E/44, RG-380E/60 and RG-390E series of heated batteries incorporate internal AC (115 V nominal) and DC (28 V nominal) heater blankets that surround cells in the most optimal manner for equalizing cell heating. These blankets are controlled by a Heater Control Unit (HCU) offered in four TSO authorized varieties. Some airframe manufacturers have already incorporated this design into their aircraft to provide end users with optimal performance and zero inconvenience.
Concorde’s RG® Series batteries perform in temperatures ranging from -40° C to 71° C. Although heated batteries are the best solution for sustained cold weather operation, when Concorde’s heated batteries are not approved in your aircraft you can still be confident in their starting capacity under the most extreme conditions just like Kenn Borek trusted Concorde’s RG-380E/44 during their mission to the South Pole.
Concorde Battery Corporation supplies over 100 models of original equipment and direct replacement valve regulated sealed lead acid batteries for fixed wing, rotorcraft, and unmanned aircraft. Concorde batteries are installed as original equipment by the majority of aircraft manufacturers and adopted by military aircraft operators worldwide.
