You didn't mention the converter make/model, so I'm guessing. However, many "smart" converter/chargers will refuse to charge a battery it thinks it may be internally shorted or has a dead cell, and a dead battery often looks like that. Especially if the cell is out of water. I'm guessing you fiddled with it until the battery got enough charge to look ok and the charger went back to normal charging again.
