My wife noticed a strong odor she described as sewage smell yesterday near the motorhome.
I probed around and found the middle of three batteries very hot and four cells dry. I unhooked them all and removed them.
They were serviced about three weeks ago and a little water was added to each, no huge amount to any one battery.
Batteries were purchased 2/2012 and are Interstate Group 29 batteries.
Converter/inverter/charger is Dimension 2000 watt.
Rig is a 2005 Itasca Meridian 36G that I bought new in '05.
My thinking is I have one battery that has gone south due to internal failure and it is not a bad charger.
The batteries are still on prorated warranty and will probably replace all three especially if testing shows any weakness of the other two.
My question is twofold.
1. Can I tape the leads and put external power on? Our house has sold and we need power so we can pack it up.
2. Do you electronics wizards agree with my thoughts that the battery is bad and not he charger? I'm no wizard but think more than one battery would go belly up if the charger was bad.
Thanks in advance.

True. My manual even says to use the battery disconnect switch when connected to shore power for an extended period of time.
I don't do that but do check the electrolyte level in the batteries each month.

I would just use / connect one of the three 12 v batteries until You get around to replacing them all!
You should be able to tell which one of the three is working properly with a simple hydrometer test.

Hi Doug,
So the batteries were connected to a buss bar with equal length cables?

Thanks guys.
Yes, they were hooked up just like they came from Winnie. I took pictures years ago and check them every time.

Hi,
With a modern converter you can use it without a battery--but don't try to power things such as slides.
Were the three batteries wired in a balanced manner?

You can use shore power without the battreies...
I believe the bad battery is the problem (dead short or dead cells) not the charger...
