Hi, the past few days my Accord has been slow to start up, but still started, and today it started slow but then quit. Now it makes a ticking noise when I try and start it. The radio still works, so my guess is it's not the battery, but what do I know... any help would be greatly appreciated.

I would begin by removing and fully charging the battery. Clean battery terminals and cable connections well. Most auto parts stores will test and charge batteries for free. This link may help:

My bet is that the battery needs replacing.
