Battery going out this soon?

if you had been recharging your battery every day and not let it discharge so deeply in the first 4 days you would not be having this problem.
you are damaging the battery every time you let it get that low evan at home in storage.

the voltage gauge supplied in most rv's is not a good indicator of state of charge on your battery try testing it when the water pump is running and the battery has a load on it.

“and got it full in 2-hour run.“

Your battery was not filled after a two hour generator run. The absorption phase takes longer than that amount of time. How long after you stopped charging did you take the reading? How did you take the reading?

You did not "get it full" in two hours of genset time, I can almost garentee .

You didn't get anywhere close to a full charge in two hours.

Again, thanks everyone for the comments and suggestions.

Learned a lot about batteries in so short a time. Forgot that we have an electrical engineer and someone who works on batteries (Tesla), lol.

Forgot too the conventional wisdom among scientists. That if you are finding solution to a problem, look at the simplest first. The advice I got, first, check the terminal connections if loose and 2nd, check the battery if it's gone bad.

And my problem indeed is the battery. As my in-house expert said, 2 to 5% of those will be bad right out of the factory floor -- and unfortunately, a few will not be detected in quality control and testing and will end up in our hands and mess up our time under the trees and with the mountains.

Lwiddis is right, batteries have life cycles and will die if it reach it's limit. Our RV's deep cycle batteries are meant to go on deep discharge, hence, the name, duh. It is not supposed to die or go bad immediately if it's fully discharged, but the deeper the discharge, the shorter the life cycle. Extreme heat is also the enemy and so as residues falling at the bottom and accumulating to touch plates.

And yesterday was the more difficult task. I must have made more than a dozen calls to the CW dealer, salesman, service department, Dutchmen (manufacturer), battery dealer... for anyone to honor their warranty.

In desperation, end of the rope post for, Ella/Ask Marcus. Wish me luck!

Need a voltage reading or hydrometer to verify full charge.
Good chance the battery has never been fully charged and has sulfated.
Very common in part-time RV use.

Actually you need to check the converter output to the battery before you assume the battery is at fault. It may be shot now, but the base cause could be that it wasn't being charged due to the converter not operating as it should.

Man i feel for you.

I just replaced the bat in my 5er. It had an 09 date on it.
