Battery

[photoperkins]

I have a 2023 341 rds. I am wondering if anyone has had an issue with the battery over heating. When I first got the unit the battery got hot and acid came out. They changed the battery once. I sense had the battery push acid out twice. The highest charging was at 1450. Just for a little while. I just noticed the battery issue again the charging was around 1325. It’s in storage right now I was told to just unhook the battery. But I’m wondering if there might be an issue somewhere that I might need to look at.
Thanks for the help

Do you mean "14.5" volts, rather than 1450? And "13.25" volts, rather than 1325? Do you mean you have had the battery "push out acid twice" since you got the new one? Can you describe when the battery got hot? In storage, or in use while plugged into shore power?

Yes, I would think if the battery "got hot and acid came out", you have a problem, which may be causing over charging. What kind and size battery do you have? Sounds like a flooded cell battery, which is about the cheapest battery they can put in.

Yes I forgot the point, ya the battery has pushed it out twice I’m going to get it checked to see if it is bad now. But I was just wondering if there is something elsewhere that I might be missing. It’s parked in my driveway winterized I did have it plugged in for a little while but it’s unplugged now the heater seemed to be trying to run so I unplugged it that’s another question itself. I looked to make sure i didn’t have the heater on everything was off. The battery issue again a deep cycle lead acid battery I am thinking about putting in a sealed gel battery but didn’t want to mess it up if there is something I need to check

The voltages you list are not excessive so that doesn't seem to be the issue. However, just to be certain, you might want to check your meter source in case it is reading low. If the converter/charger is working correctly, perhaps it's just a bad battery. Still seems odd given the voltages you state but stranger things have happened I suppose. I prefer the convenience of AGM vs flooded where I haven't upgraded to LFP, but before you invest in a new battery of any type I suggest just confirming that your charger is working correctly so you don't end up burning up another battery. Or, buy the new battery and watch it closely so you can catch it before the charger does try to overcharge it. Good luck!

The converter monitors current draw to determine the state of charge of the battery. As a good battery nears full charge, the current drops and the converter responds by reducing the output voltage.

If the battery is sulfated, otherwise damaged, or low on water, the current never drops so the charger remains at the higher charging voltage and vigorous gassing occurs expelling electrolyte. The converter can be “fooled” by a current draw in the trailer which causes the voltage to remain high.

Not out of the question that the converter is bad.

Thanks I really do appreciate the help

Very good clarification about how it works if the battery has gone bad.

Were would the converter location possibly be there is a black box in the front compartment I think it’s part of the solar

Likely behind the basement wall near the breaker panel
