Battery was dead but then the car started up
Two/Three days ago, my car battery was dead (I apparently left the
headlights on overnight for roughly 12 hours, even though I don't remember
doing that, so I know for sure the battery must have been dead or
something), I left it in the parking lot for a couple days until I could get it jump
started. Today, I was looking for something in the back of my car and by
habit, I used the unlock button on my key fob and noticed that it actually
unlocked my car, so out of curiosity, I tried starting my car and it worked. I'm
wondering what the reason for this could be? Was it possible that the battery
wasn't completely dead but just didn't have enough to start the car?
Batteries can recover a certain amount of charge if left to sit.
