Can lead-acid batteries release CO? Or can a CO sensor detect …
Lead-acid batteries produce Hydrogen when charging. Carbon Monoxide detectors use something called a "Metal Oxide Semiconductor (MOS)" sensor, which detects a variety of gases including Hydrogen. A MOS sensor calibrated for CO will give a false positive in the presence of Hydrogen gas at ~10% of the actual value.
