BATTERIES MEASURING 3/4 ON PANEL LED CHECK

On my TT I have two batteries that were installed by the dealer when I purchased my RV in 2016. These have always been plugged into power, and I have added distilled water as necessary. Now for the first time when I press the panel LED battery check button, I get 3 out of 4 LED's. These are lead acid batteries, so I don't think it's a question of "exercising" these batteries to get them back to 100%. Any suggestions?
thanks for any help.

    You are plugged in and getting 3/4?
    Check your battery voltage. 13.2+ indicates probably the panel has issues. 12.5 or lower you may need a new converter.

    Check voltage with a meter at battery (without trailer plugged in for at least 2 hours) and compare the reading to the chart below.
