Battery Issue

Hello,
I am new to this forum. I have a problem that I cannot figure out and need some advice. I have a 2007 Springdale rv 30'TT. Sort of a long story but I want to give the whole story.

After I winterized it last November I pulled out the battery and stored it in the basement on some wood shelves. This spring I re-installed the battery and plugged the rv into 110 shore power and left it be for a week. After a week I was doing some cleaning and noticed a acid smell coming form the battery and it was hot. I assumed my battery was shot and bought a new one. I installed the new one and did more cleaning then left it unplugged form shore for another week.

When I went back I realized I left the bathroom light on that whole time. I plugged the rv in figuring the battery needed charged even though it read 12v on my multimeter. After plugging it in I can hear the converter fan kick on and off in about 30 second intervals when it does this I also hear a click at the same time as the on and off cycle at the battery area. Here's where my questions come:

1. Is this normal for the converter to cycle and click at the battery area, I haven't noticed this before?

2. Is a 12v reading accurate to tell the charge of a battery?

I am nervous about keeping it plugged in so I don't fry a new battery.

Any help would be great!

  • You need to determine the output of your converter to see if it will fry the battery. Disconnect the battery (take both battery cables off of the battery), plug the TT in, read the output voltage of the converter at the battery cables. Should be something like 13.5 to 14 volts. If its to high it will fry the battery (not sure how high it can be without damaging the battery). If it's too high you have to replace the converter.

    If you left a light on for a week then the battery is very low. Its likely the clicking is a self reseting circuit breaker being overwhelmed by the high amp output of the converter. It common for the manufacturer to undersize thiese circuit breakers. I would look into this. This is causing the converter to cycle. Do you have a battery charger?
