Battery dies after sitting for only 10-14 hours
New to the forum...I'm actually driving my mom's '00 Outback for the summer. Anyhow, I've searched the forum and it sounds like a parasitic drain is fairly common, however, all the posts I saw related to a dead battery after the car was left sitting for a week or more.
So, story is that the car has been driving fine for a month and when I went to leave work a few days ago the car wouldn't start (after sitting from 8am til 5pm). Jumped it off and drove home fine then it wouldn't start the next morning. Took it to Napa to check the battery and it had 12.09 volts when turned off. Dropped it off at the mechanic near work in the morning for them to charge it up (my mistake was not checking the voltage after they charged it). Car was fine when I left to go home from work that afternoon, but was dead the next morning. I was getting 13-14 volts at idle so I figured it was the battery. Purchased a new battery yesterday morning and it was fine the whole day then...yep...it was dead this morning. Any thoughts?
I've had alternator problems on cars before, but the symptom of that was that the car died while driving...this time the car runs fine while driving. As a note, yesterday before I bought the new battery, the ABS light was on / off intermittently after jumping the car and on the way to work after buying the battery. But it has stayed off since I parked it at work yesterday, so I chalked it up to the car just needing to sort itself out after getting a new battery.
TIA for any help! Art
