Concorde RG Series Batteries with AC & DC Powered Heaters optimize performance and convenience for cold weather operators. Removing batteries and storing them, reinstalling prior to departure or using an external heater blanket still results in diminished capacity & disproportionate recharge across battery cells. Concorde's heated batteries incorporate internal AC and DC heater blankets for equalizing cell heating. Thermal switches automatically turn on or turn off depending on the temperature of the battery. Redundant switches are in place to prevent the possibility of overheating.
Some airframe manufacturers have already incorporated this design into their aircraft.
Models include RG-390E/KH & RG-390E/LH in aluminum containers and RG-390E/KSH & RG-390E/LSH in stainless steel containers.
