Tom and all,
I think I'd be more worried about corrosion issues associated with H2S gas mixing with water vapor and creating sulfuric acid (H2SO4) Mark - N9WYS From: Repeater-Builder@yahoogroups.com On Behalf Of Chris Quirk Well boats usually do not blow up or catch fire from hydorgen leaking from batteries. It is usually from gasoline vapors or leaking propane. The plastic battery box is a corrosion / spill containment issue. My Jaguar XJ8 L has the battery in the well sealed trunk of the vehicle, I have also owned several cars that the batteries were under the back seat. So Hydrogen gas and venting is a real issue but statically incidents are pretty low from what I can tell Like I said earlier there are repeaters in the same block house that mine is in and they place the batteries in the bottom of the cabinet with no real venting taking place, does not seem to be an issues and as most of the chargers are slow charge with trickle so not a lot of gas released anyway. You add to this that hydrogen rises very quickly as it is much lighter than air and you ask the question how much gas would stay in an enclosed area ? My guess is little to none. --- On Mon, 11/30/09, TGundo 2003 <tgundo2...@yahoo.com> wrote: From: TGundo 2003 <tgundo2...@yahoo.com> Subject: Re: [Repeater-Builder] Batteries for Backup- Methods To: Repeater-Builder@yahoogroups.com Date: Monday, November 30, 2009, 3:35 PM Thanks to everyone for the feedback so far! So here is what is bothering me this afternoon. Maybe someone here can shed some light on this for me. The battery I am thinking about using was one I bought a while ago for my boat, but I didn't use it because it was too big for the battery box in the boat (don't ask). I kept it knowing full well I had other uses for it. Thinking about this some more, by law any wet cell battery on a boat must be contained in a battery box. Thinking more about this, I realize that the standard plastic battery box is not really vented, nor completely sealed. In the case of my boat (24' pontoon)has two such batteries, one under the seat in the rear for the motor and the other under the seat in the front for the trolling motor. The compartments under the seats are enclosures in and of themselves. The rear one is charging off the engine during run time. On an afternoon cruise it could run for several hours charging the battery the whole time. So the wet cell battery, in the box by law, is charging in a box with little ventalation. Are boat owners everywhere sitting on ticking hydrogen bombs? Tom W9SRV No virus found in this incoming message.
