It's cold outside, and my 6 month old batteries are dead.

No lights were left on, no doors were left open (if that could even be an issue since my Ford's lights go off after 10 minutes to save the battery anyway).  After getting the batteries charged, I put them in and hope the alternator would do the rest.  I left my car running for an hour... Perfect!  The battery's voltage tested at 14.4v while running.  Then I turned the car off.  The voltage dropped to 12.6v, what a fine resting voltage you may think....  After waiting a minute or so, I started to notice that every 5-10 seconds, the voltage dropped by .01v.  This was odd, and I'm wondering what's up.  I'd love someone to tell me a problem like this is covered under the warranty.  Poor college students can't afford XS batts every six months....  I might add that none of my friends' cars have had a problem starting.

 

Just wondering what's up.  Not really sure, and I need to get to work to pay for my educacion.

Do they do the same disconnected? Parasitic draws are a bitch, but the first step is isolating the batteries.
