Lights dimming in Jayco TT
I have a 2012 Jayco TT that we are living in while building our house. I have noticed there are times that the lights will dim and then brighten back. When this has occurred the air is off, water heat...

I have checked the battery and all cells are full. I did see a small amount of corrosion on one of the terminals. I will clean that this week. Thanks for all the input.
Checking water levels is about 10% of the job. There are numerous ways batteries can become a problem or fail, water level being just one.
The next step is to take those batteries down to the nearest AutoZone, Pep Boys, O'Reilly's or whatever you have in your neck of the woods and ask them to test them. They will put a load tester on them and test for proper performance for free.
Last time my rig's battery died, the water levels were fine, a volt meter showed full charge, after the gauge in the trailer said they were full, too. But when I'd turn on a light inside, it would come on, burn for about 30 seconds, and then fade out black. Wall gauge would show full charge, still. But when I took it down to AutoZone, their tester revealed that while it had full voltage, it was incapable of actually delivering more than a trickle of current. A new battery fixed everything.
naturist,
Absolutely. I too have experienced a bad battery, granted it was a motorcycle battery, where it would test perfect with standing voltage (12.5V) but hook it to a load, and voltage reading was around 7V.
A load test is the only true way to determine if the battery is good or bad. Almost every automotive location will have a battery load tester, including places like Walmart.
