Basically my battery keeps draining for some reason and recently it happens around 1 week after inactivity. The battery is relatively new and the alternator is still good.
Will provide more details to the best of my knowledge upon request.
Google parasitic draw test and do that. It could be lots of things, w/o doing that test you are just guessing. It could even be the alt if the diode packs are bad, so don't rule it out.
