If you use the 12v sockets, it will slowly drain the battery. But it's hard to say undoubtedly when not seeing that particular accessory. For example, a few devices do have a LED light in the cigarette lighter plug. It will continue to draw power even when the accessory is not working. Of course, you can cut off the cables, why not. But it will take nearly four months before it will be completely drained. Is it not acceptable in your case? As for my friend, he hired a guy from the local electrical https://bates-electric.com/locations/chicago-il/ company who has solved the problem with the cables.

My friend used to have the same model, the batter trick charger worked perfectly for him.
