All the Smart-UPS outlets are battery protected.
Without knowing what cable you are using (part number is on the cable) and what version of Powerchute you are using (some versions/modes of operation will not display a load value) we are guessing at your problem and solution.
Having no load lights on the UPS is not unusual, as already pointed out, the lights step on when the appropriate load level is reached, the 5 lights each represent 20% of the overall load, until you reach 20% the light will not come on.
