If there are interruptions to the power supply to the charger, or if the voltage to the charger drops below 90V even temporarily, the charger resets itself to a \Charge Complete\ mode. If this is happening you will need a regulating switching supply from Quest which will constantly output the necessary voltage even if the input voltage drops below 90V (part numbers 060-095 Line Cord and 054-721 Power Supply).
