I drove my car to work the other day and when I got out six hours later my car wouldn't start, got a jump drove home and went to bed. Next day after my car sat for about 13 hours went to start it fired right up. Went to carls jr 3 hours later and it started right up. Went to start it up an hour and a half later to go to work, and battery is dead again. I haven't done anything that would drain the battery like leave on my parking lights or interior lights so I am stumped. I have noticed that both times that the battery died that the cooling fan was blowing when I had parked it beforehand. For now I am disconnecting the battery when I park so it wont die on me.

 

Sounds like your car does not like your place of WORK. JK. How old is your battery? Maybe you should have it tested or just replace it if it's over 3 years old. $100 Is a small price to pay to get around without worrying about your battery dying.
