The problem you describe would occur with any car that receives so little use. It is extremely unlikely that this would be covered under warranty.
 
A trickle charger would be a possible solution.

This article: http://www.ehow.com/how_4897932_trickle-charge-car-battery.html
indicates loss of up to 2% per day, so it would seem like even starting once per month would be sufficient? Of course, then the question is how long does it need to be driven to get back up to near full charge? I'm guessing that driving once per day for 3 miles is probably more of a problem for a battery than driving once per week for 20 miles.
 
Maybe a charger that plugs into the cigarette lighter/accessory socket would be a fairly convenient solution?

Trickle charger for sure. That's just not enough driving to keep the battery charged. You should be able to wire it up so it can be plugged in through the front grille without opening the hood.

After sitting36hrs, the mercury Milan won't start. We replaced the battery last week and took it to the dealer when it happened again two days later. We have no added features such as alarms or satellite radio beyond what came with the car. The car is less than a year old. The dealer could not find the problem. Any ideas?

Could be a short or a bad radio, etc. Turn everything off and wait at least 30 minutes. Then check the current draw. If it's more than 0 start pulling fuses one at a time until it stops. That will tell you which circuit is drawing current. If pulling fuses doesn't stop it then it's a short somewhere which is harder to find.

"That will tell you which circuit is drawing current. If pulling fuses doesn't stop it then it's a short somewhere which is harder to find."
 
That is good advice, but i would add that to pull more than one fuse on related circuits, if pulling one at a time doesn't work.
 i.e. - on the ESP, it may be related to the ABS circuit.
 - mirror heaters related to rear defogger
- if it has speed sensitive wipers or volume on the radio, then check the ECM speed sensor against the wipers and/or stereo circuits
 
etc
 
A competent dlr would know this. I would go elsewhere, then go back and tell them that a dif dlr fixed it by troubleshooting the obvious. Then I would write Ford and ask them why one dlrship was able to fix it right away, yet the other says we don't know.
 
I guess my patience is wearing thin with so-called mechanics and service/wty depts that are paid really really good wages (at least the dlr charges high rates of 80 to 90 an hour and more) and are educated on the very brand they work on, yet are so quick to offer the corporate excuse "we don't know where the problem is" or the other famous BP raiser..."they all do that"..

Recently, I read that the car should be run at least every 30 days, otherwise the battery can be depleted.
There a lot of electrical systems still active even though the car is off.

Try removing the bulb from the trunk light - my light was staying on due to a faulty switch and draining my battery slowly; had a dead battery when not driving for a few days... use a camera in the trunk with the video recording to check.
