The electrochemical gas detectors are not entirely interference free
so sulfuric acid mist or SO2 may have simulated CO. I never saw it
around batteries, but NOx interfered with the old Ecolyzers (the
original electrochemical gas instrument) while CO interfered with the
Enolyzer (a follow on for NOx from the same manufacturer).
Maybe the battery got hot enough to cook organics enough to create CO.
