Exploring the Car Trouble

Had the same kind of car trouble yesterday when I went to head over to the post office, so today I worked on trying to figure out exactly what was wrong with it. I tried starting it up and once again it had a hard time getting going, so after a bunch of research online and trying out my digital multimeter on the battery, I determined that the battery has a very low charge. I tried idling the car for over an hour, but it didn't help very much, so tomorrow I think I'll take it in to get the battery tested.
