Battery life for a non-rechargeable TruDefender at room temperature is which of the following?

• A. 3 hours
• B. 6 hours
• C. 4 hours
• D. 5 hours

Answer: (D)

Battery life depends on energy stored in the battery and how much current the device draws during use. For a non-rechargeable TruDefender, the pack is sized to provide about five hours of operation at room temperature under typical use, balancing field needs with a compact, lightweight design. If you engage more demanding modes, keep the display active, or trigger frequent alarms, the current draw goes up and the runtime can drop below five hours. Conversely, lighter use or operating closer to standard room temperature helps maintain that conservative five-hour expectation. Since the battery isn’t rechargeable, you replace the pack when its energy is exhausted.
