Don't know who told you this old wive's tale? (And you are aware that AGM batteries have lead-acid chemistry?)

Even if it's only for an exceptional circumstance, (e.g., battery or charging system malfunction), having a vent sure seems like a good idea to me when the battery is located in an area without plenty of natural ventilation, (and where sulphuric acid vapor-induced corrosion would be so damaging and expensive to repair) like is the case on our cars...

Nice find! That looks just like what I've got on my AGM battery...
