Will my electric trailer jack work if the battery is dead and my truck is connected via 7 prong connector.

My electric jack will work if the battery is dead when hooked to the 7 pin connector on the truck. Found this out the hard way. Forgot to turn off the battery disconnect switch and killed the battery, so had to plug in to get the elec jack to work the next time I went to hook up. Jack worked fine then.
