Backup Battery

A backup battery is a secondary power source that provides power to critical aircraft systems in the event of a primary power failure. Backup batteries are typically used in aircraft to power essential systems such as flight instruments, communication equipment, and emergency lighting. These batteries are designed to provide power for a limited amount of time, typically between 30 minutes to an hour, to allow the pilot to safely land the aircraft or to activate emergency systems. Backup batteries are an important safety feature in aviation, as they provide redundancy and ensure that critical systems remain operational in the event of a power failure.
