Hi, my car wouldn't start the other day. I figured it was the battery since it was old. The car didn't even make a noice. The battery was making a clicking noise. At least I think it was the battery. I had the battery replaced yesterday, and it started up just fine. I drove it a little bit. Then this morning it was completely dead again. I wasn't even able to use my car opener. It didn't work. It seems like something is draining it. What do you think it may be? Thanks!
