I bought the car brand new in May of 2009. All was good until February of last year when the battery died. Since I live in Anchorage, AK, and we were in the middle of a good cold snap, I kind of wrote it off as one of those things that's part of life in AK. But then the same thing happened in November - yes, it was cold again, but it died after I'd successfully started it and drove it to my husband's work. He was inside for maybe thirty minutes. Not wanting to waste gas, it turned the car off and listened to the radio. When hubby came back, I tried to start the car and ... nothing. We had to get it jumped. Hubby said I shouldn't have been listening to the radio with the engine off. (For maybe 20 minutes? Really??) Anyway, I had a service appointment at the dealership a few days later and mentioned that the battery died again. They checked it and said it was weak so they replaced it.
Now, of course, I'm super-paranoid about everything that could be draining the battery. I turn the lights off whenever I turn off the engine (even though that's supposed to be something the car does automatically), and only listen to the radio when I'm driving. I've made sure that there's nothing plugged in any of the power outlets, and I don't have anything that's after-market. Oh, and middle of last year the radio/CD player died too, and that had to be replaced. Don't know if it's linked, but it's still odd.
The only suggestion the dealership had was to drive it more. I guess I'm pretty severe on the car - work's maybe a fifteen minute drive (20 if it's snowing) and a fair few of my journeys are short ones, for a variety of reasons. Plus, it's Anchorage, AK. Severe driving's standard here. But I never had these issues with my other cars, and my driving patterns haven't changed at all. Could there be something that's draining the battery that I haven't thought of, or am I really stuck with driving around Anchorage aimlessly for at least 20 minutes each time I get in the car?
