Our previous posts crossed. Most of the considerable number of experiences quoted in your second involve starting a car (or, occasionally, a boat) engine a few minutes after it's been previously going and presumably (over)charging the battery, causing gassing. This scenario is understandable (if rather disconcerting for the participants!)
I still fail to understand where the hydrogen is supposed to come from in the scenario of a battery being unused or discharged for hours / days / weeks.
