Commercial Aircraft Batteries are used to start engines while initiating taxiing and auxiliary power units (APUs) for a variety of functions, such as acting as a buffer in regulating DC network voltage, and ensuring acceptable power quality for the equipment connected to it. In case of in-flight general electrical failure, the aircraft depends on batteries to power the essential loads until landing and evacuation.
