My Dual Pro Quad charger draws 3.63 mA from each 12V battery. At that rate, assuming 105 AH batteries like mine, it would take over three years of having the charger connected, but not plugged into AC to drain the batteries. The internal self-discharge rate of the batteries is likely higher than that. ...Pat

If it did I would assume milliamps but that could be an issue if the ac power was off for any length of time. I hate to leave the dock power hooked up if there is no need for extended periods.
