Since my car is probably going to be sitting for a while waiting repairs, how often should I go out and start it up and let it run? Right now I've been starting it every other day and letting it run for about 5 minutes. Is this enough, not enough, more than enough? I just don't want to get stuck with a dead car before getting it fixed.

Hook it up to a battery charger (I use a Battery Tender) or remove it and bring it inside. __________________ I scream, you scream, we all scream for ZOMBIES. | | | 03-24-2008, 01:13 AM | #5 | Senior Member Join Date: Mar 2008 Location: Omaha, NE Posts: 737 | Quote: Originally Posted by tiFreak +1, if you don't feel like taking the battery out though, you could just hook up a trickle charger, is the car sitting indoors? | Car is outside. It's been less than a week since the accident, and I should find out in the next day or so if I'm approved for the loan to get it fixed. If I'm not, I'm probably going to have it towed home (it's at my aunt's right now, a couple blocks from the body shop) and put in our garage (not connected to the house). If I end up dropping it in the garage, I'll pull the battery. If that's the case, what all needs to be reinitialized when I put the battery back in, power windows, sunroof, radio code? Anything else I should be aware of before pulling the battery if I have to? Thanks again.
