Sounds like a drain.
First thing, remove negative battery terminal, connect one end of test light to the negative cable, and then touch the negative terminal with the test light, if the test light lights up, there's a battery drain. This would be the best way to check for sure. Reason for this, if there's any drain in the vehicle, the ground has to be used, so if you put the test light between the ground cable and the negative terminal, well you know that something is being grounded (aka, used). Hope you understand how that works
If the test light lit up then....
With the key off check the fuses. All electronic devices possible turned off, so close the door, and keep the glove compartement light off if applicable. If one has power then you have a battery drain.
