The UPS self test feature is preformed automatically when the UPS has access to acceptable line voltage. If
the battery voltage is less than 10VDC the unit will consider the battery as abnormal and fail the test. If the
battery voltage is above 10VDC the UPS will initiate a 6 second battery charge.
Once the UPS is turned on via the ON / OFF button if the battery voltage drops below 18VDC the battery will be
considered abnormal.
