When I went to a breakfast gathering in Little Tokyo, I made a stupid mistake. I forgot to turn off the headlight of a rent-a-car. It was a small car, Toyota Yaris. I rented this because I was told that it is the most economical car they have. However, I had to operate everything by manually. I didn't mind that, actually, I liked it. Three hours later, I came back to the car and found that the battery was totally flat. Even though, I had a little trouble, I was an optimistic about the incident. It was nothing to worry about, wait thirty minutes or an hour and the battery will be bring back to life. Therefor, I waited and waited. Thirty minutes passed, an hour, two hours, but still the battery was flat. Finally, I gave up and called auto club. Later. I found that the battery was old, It was almost time to change to new one. May be that the reason the battery didn't recover by just waiting.
