That is certainly an interesting notion, since I am alive after many hours cocooned with two 105 AH batteries on a Nor'Sea 27. The only gas I know about is hydrogen produced during charging, but it is of course not toxic and is much lighter than air, and it would take a massive charging rate on huge batteries to make it explosive. The technical rationale behind this caution would be most interesting.

Hi guys,

I was showing our M17 to a fellow interested in purchasing a new one and he was alarmed that the two batteries (I added a 2nd battery and a 1/2/all selector switch to be prepared for the group San Juan trip) were not gel cell type, but rather the traditional marine deep cycle trolling motor type wet cell. He said it was a big no to use that type of battery in an area where you sleep.

What do you guys think? With ventilation, is the outgassing from these batteries a possible danger for us?

Thanks

Rick
