Any converter will work fine all Winter.
That's not true. Single stage ones will tend to over-charge and "use" water.
If you have a multi-stage converter you should be fine. Check the water level going in and don't worry.
Or throw the battery disconnect switch and connect a small smart charger.
If fully charged, they might last the winter with no attention but there is a small risk in that and making sure they stay charged is better.
Sam's correct. All converters are not equal. Better to disconnect the battery and put smart charger on.
