The PRC-90-2's battery life decreases in higher temperatures. What is its life at 100 degrees?

The PRC-90-2 survival radio is designed for use in various environmental conditions, and its battery life can indeed be affected by temperature. At higher temperatures, the chemical reactions within the battery can become less efficient, resulting in a reduced operating time. Specifically, at 100 degrees Fahrenheit, the battery life of the PRC-90-2 is rated at approximately 3 hours.

This rating is based on the known performance characteristics of the device under extreme temperature conditions. Understanding how temperature affects battery life is crucial for effective operation, especially in survival scenarios where maintaining communication is essential.

The other durations listed in the choices exceed the established limit at high temperatures, reflecting an unrealistic expectation of battery performance under those conditions. The choice of 3 hours accurately reflects the limitations imposed by the environmental temperature on the battery's output.
