What is the specification for the APU BATTERY?

The specification for the APU battery is 24 DC Volts and 43 Amps, which aligns with the requirements for providing sufficient power to the auxiliary power unit (APU) while also enabling it to perform effectively without compromising the aircraft's systems. The 24 volts is a standard voltage for aircraft batteries, ensuring compatibility with the primary electrical systems, while the 43 amps rating allows for adequate power delivery to support various APU functions, including starting and operating. This combination is designed to provide reliable performance under typical operational conditions in aircraft, making it an essential aspect of the aircraft's electrical system.
