The batteries are probably just fine. I won't go into the "why" the converter will not bring them back up at this point. Assuming the water level was adequate at the point you put them on the Smart Charger, the charger should roughly be in the vicinity of 13.2 volts in the very beginning. It should increase by a tenth of a volt over an extended period of time reaching a maximum of about 16.0 volts near the end of the process, doing this equalizes the cells. This will take the batteries to approx. 85-90 % capacity, at which point the charger will probably back off. Remove the charger. Put a load on them using a 12 volt utility light for a couple hours or a load tester for about 10 seconds & let the batteries "rest" afterwards for a few hours. This will remove any existing surface charge present. Afterwards, put them back on the charger & it should bring them to 100% in a short period of time.
