What is the minimum voltage required during a battery check?

The minimum voltage required during a battery check is crucial for ensuring that the battery has adequate capacity to perform its functions reliably. In the context of the F/A-18 E/F aircraft, the standard for battery voltage checks is set at 23.5 volts. This threshold ensures that the battery is in good condition to start the aircraft and power essential systems.

A voltage reading below this level could indicate that the battery is undercharged or potentially failing, which could lead to problems during aircraft operation. Ensuring that the battery maintains at least 23.5 volts is vital for the overall safety and functionality of the aircraft's electrical systems.
