This CucsEquipmentSensorThresholdStatus reports the RTC battery's voltage sensor threshold status, flagging whether the battery's output voltage has crossed a defined low or high limit - the single most direct indicator that a coin-cell battery is nearing end of life, since voltage sag is the classic failure symptom for this component type. An admin proactively replacing batteries before they cause BIOS clock resets watches specifically for this field moving out of 'ok'. A value of 'lowerNonCritical' would be an early warning that the battery voltage is starting to sag and a replacement should be scheduled.
