car won't start, lights work

What is your question?

Car won't crank. Lights work. Just changed battery. Actually they put battery in wrong which blew the fuse. Fixed the fuse and car ran but still had trouble starting like it had been doing before changing the battery. Then yesterday when we went to store it just wouldn't turn over. Tried to hook it up to jumper cables which only seemed to make it worse. Because it was trying to turn over and now it won't do anything. The lights come on but it doesn't make a sound when you turn the key.

What makes this problem better or worse?

Nothing

How long has your 2007 Honda Accord had this problem?

Starting problems for a month or so. But not cranking at all since yesterday.
