I've used mine for two years now through the rear jack. The lights on the charger indicate it is recognizing that a battery is present, hooked up properly and then goes into the appropriate charge cycle, either full charge, 80% trickle or monitoring. I don't think it could do all of this if it was not connected to the battery. Like the others have said, I'd stay with it.
