I don’t think there is a problem with draining your batteries all the way down except that deep cycles greatly reduce the life of the battery, but this has nothing to do with hard sulfation where a battery is left for a month at partial charge.  Lets say you draw the batteries down 100% on each cycle Then your battery might cycle like this 100 times (as an example).  If you only draw down 50% then it cycles (500) times. If you only draw down 25% then it can cycle (2500 times)… 10%(10,000) times get the picture? Those are not real numbers by the way, just an example.
