Question Battery charge V8

As an owner of a new Genesis 2011 4.6l Sedan, I have been getting vague answers from my dealer and Hyundai Customer Service concerning the following :
When I park my vehicle in an airport parking lot for a three weeks out-of-town trip, should it start without a problem upon my return?
What is a realistic time period that the Genesis can be parked before start-up? There are recommendations that for "long term storage" a battery maintainer should be connected which is easily done in one's own garage.

I leave vehicles sit for 6 months without starting and they are fine. You may have too many things that continue to run like the clock and alarm system. Just guessing here. You could disconnect the battery next trip but then you need to reset everything which is a PITA to reprogram the radio ETC.

wwtraveler, your Genesis sedan along with a few other vehicles by Hyundai (Equus, Veracruz & Entourage) have an array of electronic devices that draw on the vehicle even when shut off. Due to issues with these vehicles going dead while on the sales lot, Hyundai issues a TSB to crank the vehicles every couple of days or pull the stunt fuse out to disable most of the components.

I've got a crappy version that plugs into the cigarette lighter lying somewhere in a box. It actually came with VW pre-deliveries at the store next door & was given to me.

My 2009 Genesis has a dead battery if I go 2 or more days without starting it. I travel frequently so at airports I often have a dead battery. The problem just started a couple of months ago. First time it happened I replaced the battery (car was about 3 years old with a 36-month battery), but the very next time I went to the airport the same thing happened. First trip to the dealer they looked at it, "cleared some error codes" and told me it was OK. It wasn't, so on the 2nd trip to the dealer they told me I had a bad battery (the new one). Autozone (where I bought it) told me the battery was fine. I tested it myself, disconnecting the battery cable and letting it sit for 2 days it was still at 12.4 volts. When connecting the cable it dropped to 9 volts in 24 hours and was dead in 48. So back to the dealer. This time they replaced a "Fornt Area Module". Got the car back 2 days ago, left it in the garage, this morning the battery is down to 7 volts.
Any thoughts? This is getting really frustrating.
Thanks!

It is very hard to track down an errant current drain. Here's how to do it.

You need an amp meter between the negative cable and the battery post. Then it needs to be mounted so you can see it while you start to pull fuses. You are looking for a drop. Seeing as some current drain is normal this can be quite frustration. Usually the nominal current drain is less that a 100mA.

So with the battery draining down over night the drain is going to be bigger than that. Just start pulling the fuses and see if you can narrow down the circuit.
