What is the battery life of a SART in standby mode?

The battery life of a Search and Rescue Transponder (SART) in standby mode is indeed 96 hours. This extended battery life is essential for emergency situations, ensuring that the device can remain operational over a longer period when it is most needed.

In standby mode, the SART conserves energy while still being ready to activate quickly when necessary. This allows it to respond effectively to distress signals from vessels in need of assistance while ensuring it can remain available for a significant duration. A longer battery life significantly enhances the chances of successful rescue operations, as it increases the window of time during which a SART can be activated and provide precise location tracking for rescuers.

In contrast, the other options suggest shorter battery durations, which are not optimal for the critical role that SART devices serve in maritime safety. The design and specifications of a SART prioritize readiness and reliability, which is why a 96-hour standby period is both a practical and necessary performance characteristic.
