Bad sulfer smell from battery

[dentra]

I have a 2005 Fleetwood Newport and had it plugged into 110v ac and the next morning I noticed a bad sulfer (rotten egg) smell around the camper I took off the battery cover and found the battery hot and a little smoke comming off of it so I disconnected it! was wondering if there is any type of regulator to stop charging the 12v battery when it is full? hoping the battery was just overcharged (and not fried) !!!

Its fried! Google "battery minder" and you will find what you need. You didn't necessarily overcharge your batteries if they are the original. They may have just given up at 5-6 years old.

It's more likely the battery has a dead cell which prevents full charge so the converter keeps charging and boils the battery. Check the specific gravity of each cell and/or battery voltage without being plugged in.

Yes, they are most likely finished. The battery acid / water is cooked out of them. It has happened to me twice now. I have had to replace my battery twice in my 05' Aerolite hybrid. I'm going to pay more attention in keeping the battery water level filled. Deep cycle battery's don't last like car battery's...period

yes your battery is probably shot. but you got the expected life out of them. there are better batteries out there if you want but you pay for them. Optima and others now make a gel deep cell battery that is closed and won't boil. the life expectancy is supposedly longer but again you pay for it. do your research and keep us in the loop.
