Battery low after camping

My wife and I purchased a 180 last year. We’ve noticed an issue with our battery charging and I’m not sure why this is occurring.

When the trailer is parked at our storage facility we have it plugged into a standard 110V volt household outlet to keep the battery charged. Whenever we start a trip the battery indicator shows “Good.” We tow to our campsite running the fridge off battery, then connect to 30 AMP shore power. We are usually connected to shore power for two to three days. When we break down camp and disconnect the shore power the battery indicator always shows “Low.”

My question is, why would the battery successfully charge at the storage facility over a few days, but not charge while hooked up to 30 AMP shore power at a campsite?

Any input would be very much appreciated!

Thanks,

Matt

It would be good to get a circuit analyzer. The power pole might not be wired correctly. I had that happen. I have the Camco Heavy Duty Dogbone RV Circuit Analyzer. It caught the defective pole so I was able to move to a different site.

I run my fridge on battery when traveling, my TV has no issues charging same. I think you need to look at the convertor and make sure all the phases are working correctly, with a low battery your convertor fan should be running and the convertor in normal or bulk mode. Check with a voltmeter and don't rely on monitor gauge.

Have you topped off the batteries with distilled water?  The batteries are hard to see in the rPod box.  I check mine 3 or 4 times a year and am always amazed at how much water each cell takes even tho I can see the surface reflection .  Be sure to use a flashlite and a turkey baster or big syringe to add water.

I have screens in the refrigerator, furnace, and water heater vents to keep wasps out. Screens act as a flame arrestor, so when I am going down the road, I do not have an open flame.
