I didn't drive my car for months.
Jump-started it once for a minor drive, but then didn't drive it again for a few weeks.
All of this happened during cold winter.
Now I jumped it again, with the intention of driving it regularly again. I let it idle for 30 minutes, and it wouldn't start again after I turned it off. I jumped it again, drove around for 45 minutes (and I forgot to turn off the AC and radio during this ride), then parked it and turned it off (and I did not try to re-start it immediately).
My question is, when I wake up tomorrow, if the car doesn't start, is that an indicator that the battery needs replacing, or should I try to jump it again and drive it around for longer with all AC and radio off?
