Ryan, The batteries were not being charged. However, I thought of that and placed the unit in the battery compartment,it remained at zero.toggle quoted messageShow quoted text

On my old boat, I saw what you experienced many, many times. I was initially extremely concerned, as one should be. But then one day my boat got unplugged from shore power by the dock staff, and that night after plugging it back in I was awakened by the CO alarm.. There had been nothing on board that produces CO in many days. After much experimentation, I proved to my own satisfaction that the CO alarm was actually sensitive to hydrogen gas produced by the batteries when they were excessively charged. It seems this is true for many CO alarms.
Take the alarm seriously. Air the boat out well, and take care not to let exhaust inside. But also check to see if your battery compartment ventilation is working correctly, and also check that your batteries aren't overcharging. Some chargers will keep the voltage too high even though the batteries are full because other loads (e.g. refrigerator) are making the charger believe the batteries are still accepting a lot of current.
