Concorde Battery is pleased to announce AW139 FAA approved STC SR03072NY, Transport Canada approved STC SH11-47 and Brazil ANAC STC 2012S04-04 replacing the standard nickel cadmium batteries with Concorde’s Sealed Lead Acid Recombinant Gas (RGÂ®), Absorbed Glass Mat (AGM) batteries.
SR03072NY, SH11-47 and 2012S04-04 replace the 27AH Nickel Cadmium auxiliary battery with a RG-407, 27AH sealed lead acid battery, and the option to convert the 44AH Nickel Cadmium starting battery with Concorde’s RG-380E/44L or the higher capacity RG-380E/60L. Some AW139 operators who requested a lead acid option conveyed a concern with slow engine starts using the standard Nickel Cadmium battery. The higher capacity RG-380E/60L is constructed with additional plates and was designed for increased cranking power, faster starts and less engine wear.
Concorde sealed lead acid RG AGM batteries are a more economical solution to Ni-Cd batteries with no maintenance requirements and reduced cost per flight hour. Sealed lead acid technology does not have a memory and does not require unique charging equipment. Concorde’s sealed lead acid batteries are HAZMAT exempt; they are proven safe and reliable with no risk of thermal runaway. Concorde RG Series batteries may be serviced in any battery facility, including nickel cadmium service facilities.
RG-407, RG-380E/44L and RG-380E/60L are FAA TSO C-173 approved and have passed the rigorous requirements of TSO testing.
