Not a lot of specifics here, but I am guessing when you are leaving it plugged in your power converter is throttling back and passing just a little current to the battery. Mine puts out .5 amps once the batteries are fully charged, but the typical power converters do not care if there is a battery on board. The one question I have is why are you leaving it plugged in. Are you leaving something running? 🙂
