Question 34D4

SART (Search and Rescue Transponder) batteries are a critical component of maritime safety equipment, essential for locating vessels or individuals in distress. To ensure their reliability and performance during an emergency, international maritime regulations (part of the GMDSS – Global Maritime Distress and Safety System) mandate that SART batteries must be replaced every five years. Furthermore, the battery must also be replaced immediately after the SART has been used, regardless of how short the activation was. Even a brief period of operation can significantly deplete the battery, making it unreliable for future emergency situations. Options A, B, and D specify incorrect replacement intervals for SARTs according to these crucial safety standards.
