Battery back up sump pump in crawl space
I purchased a Wayne battery backup sump pump to install in my crawl space. It runs off a size 27 deep cycle marine battery and stays on the charger when there is power.
Looking at the installation manual it says numerous times that charging batteries can release hydrogen gas and should only be used in well ventilated areas. I believe my crawlspace is considered to be "sealed" though I'm sure it's not air tight. So is it safe to use this charging system in a sealed crawlspace ?

Very little hydrogen will be generated when the battery is being maintained. The issue will come after a power outage and the drained battery is being more heavily charged. Technically, unless the space is well ventilated you should not be charging lead batteries. The hazard is likely minimal but the consequences if hydrogen gas accumulates and ignites could be extreme.
