          I am not aware of any chemical process that occurs during 
charging of a lead acid battery that will have CO as an end product. {At the 
same time, however, I only took one year of chemistry in high school, and 
was not exactly noted as a 'star' student. }
    At the same time, the device used to measure the CO level in the air 
might also  show sensitivity to hydrogen, or any sulfuric acid vapor that 
might be present in the air.
   I at one time had a gas / products of combustion detector in my home. 
This was when such technology was in its infancy.
         Not only did it detect all the things it was supposed to, it would 
also alarm in the presence of hair spray ,{At the opposite end of the 
house.}, and Lysol®spray disinfectant, anywhere in the house . Leaving a car 
idling outside on a cold morning,{When this thing was on the second floor.} 
would also wake it up.
    How old is this detector? If memory serves me correctly, the sensing 
element in those has a finite life time, and the unit has be replaced every 
few years.
