Using Battery Maintainer

[keysguy]

I use the Battery Tender I had to buy the cigarette adapter. I can plug it directly into the cigarette lighter port and run the thin cord out the door. I can shut the door and plug it into my extension cord. Since the cord that comes with it is thin it is not pinched when i close the door. I can leave the alarm on. You should not jump start the car through the cigarette lighter but because it's such a low voltage charge it's OK to use the battery maintainer. (from what I've been told)
