The LED battery level indicator on your RV panel tells you nothing other than glittering generalities. They are junk and have been for decades
The only way to know what your true battery charge is would be by using a hydrometer ... if battery is flooded cell type..
And charging for 2 to 3 hours is only putting a quick surface charge on the batteries and will over time result in a battery that never gets fully charged
I’d also have a multi meter to do a quick battery charge percentage test or if you have some bucks to spend a nice panel mount RV voltage meter
And if getting a stand alone dedicated meter to monitor your batteries true condition get one with a shunt..
A good simple read....
