About three weeks ago, I started to get a drain off my battery, and it will happen even if the key is off, no accessories plugged into power ports.

Welcome to 2CarPros.

That is what is called a parasitic draw. Often times, it is something simple such as a light in a glove box or under the hood. I am going to provide a link that explains how to find a draw like this and fix it. Additionally, I am going to provide links to help you when testing.

Here they are:

Let me know if this helps. Also, if you have additional questions or need help, feel free to ask.

Take care,
Joe
