Re: [PSUBS-MAILIST] Gel Cell Redue



Thanks Jay, that's good advice.  If I go with lead acid I will certainly do something to limit the risk.  You would think that they would build to chargers to fail with an open circuit so that over charging gelcells was a remote chance.  --Doug

Doug,
While I was sailing as the Engineering Officer on a square rigger years ago, we had a massive battery bank (large number of BIG batteries) in the engine room to take care of hotel loads.  These were raised about 3-4 feet above deck level in lead sheet-lined heavy wooden boxes.  The lead contained any spilled sulfuric acid or if a battery cracked.  We had a raw water suction line rupture once and flood the engine room.  The top of the battery boxes were above the water line so no battery flooding occurred thus no chlorine gas issue or batteries ruined by saltwater intrusion.  Based upon this you might still consider placing your batteries higher up than the bilge in the large sailboat you are getting ready to build.

Yea, I think that is a really good point too.  But when I think about putting them in the bilge on a boat, I keep thinking about the horror stories of chlorine gas in WWII subs. --Doug
