How can you tell if the SCBA's battery is functioning properly?

The correct way to determine if the SCBA's battery is functioning properly is by checking the indicator light. This method is effective because the indicator light is specifically designed to provide real-time feedback on the operational status of the battery. A green light typically signifies that the battery is functioning well, while an amber or red light can indicate a low battery or malfunction. This visual cue is quick and easy, making it a reliable method for users during pre-use checks.

Different methods such as feeling the battery's temperature, listening for sounds, or inspecting connections may not provide accurate information regarding the battery's actual operational status. Temperature can vary based on many factors unrelated to battery function, while beeping sounds might occur under different circumstances, and physical inspection might not reveal internal battery issues. Thus, relying on the indicator light provides a more straightforward and standardized assessment for ensuring the battery is in proper working order.
