    Question CO alarm activation from charging golf cart batteries?

    Recently my department has responded to calls were the resident's were charging there battery powered golf cart for hours at a time and the CO alarm activated. Initial readings from the residence CO alarm were in the range of 77. Does anyone have any info, or experience with this? I attempted to google this with the above heading and have had no luck. Trying to use common since, I thought that since there is no fuel driven motors involved that the CO alarm was picking up the hydrogen off gas. Is there CO off gas involved with the charging of batteries.

    Over the last few years we have had several incidents. The occupants were advised of the cause of the alarm and advised to make sure proper ventilation was in place during the charging time. We have also had a run or two with auto batteries being charged activation the CO detector.

    I've been to house CO alarms where it was the battery back up on the sump pumps that set it off , I was told it is the batteries "cooking" - they are usally warm to the touch

    Your CO sensor has a cross sensitivity to Hydrogen. Your seeing very low levels of H2 showing up on the CO side, but even though H2 is flammable you have such a low level that the LEL is less than 1. You can get sensors for some meters that "mask" hydrogen and cut down on the interfering alarms.
