Replacing a car battery

I just replaced my car's battery. That was a lot more work than I expected, partly because I had never done it before. Loosening the screw on one of the battery clamps was pretty difficult, and as it turns out, I didn't need to loosen it all that much. Also, there was this arm that was used to hold the battery in place, and this one supporting rod kept falling out of place after I installed the battery.

Now that I have the hang of it, replacing the battery should be pretty easy. I probably won't have to do that for another five years, though. In fact, my current battery lasted me for a little over six years.
