         alert (bool): When enabled and the `usb` argument is set to `true`, the Notecard will add an entry to the `health.qo` Notefile when USB power is connected or disconnected.
         calibration (float): The offset, in volts, to account for the forward voltage drop of the diode used between the battery and Notecard in either Blues- or customer-designed Notecarriers.
         hours (int): The number of hours to analyze, up to 720 (30 days).
-        mode (str): Used to set voltage thresholds based on how the Notecard will be powered, and which can be used to configure voltage-variable Notecard behavior. Each value is shorthand that assigns a battery voltage reading to a given device state like `high`, `normal`, `low`, and `dead`. NOTE: Setting voltage thresholds is not supported on the Notecard XP.

Each value is shorthand that assigns a battery voltage reading to a given device state like `high`, `normal`, `low`, and `dead`. In addition to the named presets below, a custom semicolon-separated shorthand string may be provided using any combination of the `usb`, `high`, `normal`, `low`, and `dead` states (e.g. `"usb:4.6;high:4.2;normal:3.6;low:0"`). NOTE: Setting voltage thresholds is not supported on the Notecard XP.
         name (str): Specifies an environment variable to override application default timing values.
         off (bool): Disable historic voltage trend calculations.
