Duncan Aviation added mainship and emergency power battery capabilities at 19 of its avionics satellite locations in 2020. Expanded in-house battery services at our Lincoln, NE, location include a new battery cooler, twice as much bench space and advanced test sets. Our recently opened hangar in Provo, UT, also features a battery shop with dedicated rooms for lead-acid and nickel-cadmium battery services. All of our battery shops include every test set battery charger and capacity gauge available to perform capacity checks, open circuit voltage checks, periodic checks and maintenance. Duncan Aviation also has an inventory of batteries available for exchange or outright purchase.
