Why won't my 2004 Jeep Grand Cherokee start without a jump?

Recently I haven't been driving much; less than once per day and for short distances. Less than a week ago I went to start my car and it wouldn't start. It had been starting a little slower and more rough than normal and it finally stopped starting all together. After a jump, I took it to an Advance Auto where I had the battery and alternator checked and both were said to be fine. I then drove it around briefly, filled up with gas, and came home. Over the next few days I made sure to drive around but it would always just barely start. Yesterday, when I went to start it, it was dead again. Once again, I jumped it and went back over to Advance Auto and bought a trickle charger (1 amp). I went to start the car again later that night and it didn't start. Between today and last night I charged the battery for about 8 hours. I didn't realize it when I bought it but it's not an automatic charger (doesn't stop when battery is fully charged) so I have to keep tabs on it. After the 8 hours, I tried to start it again to no avail. I jumped it once again and then hopped on the interstate and drove about 40-50 miles total. When I came back home, I turned it off and tried to turn it back on and it wouldn't start. I realize that 8 hours might not be enough to charge the battery but it seems like the jump and the driving would be enough to allow it to start on its own. I'm leaving it to charge overnight this time.

If that doesn't work (and I don't expect it to), what should I do?

Is it possible that the battery could have gone bad between the time it was checked at Advance Auto and now?
 
Iv had this problem on both my personal and a company car this winter, basicly, regardless of what an auto centre have told you, get a new battery, both instances with me, i had to get a new battery, (or reconditioned) because regardless or driving it around, or charging it, it will be dead as it has a failed cell, or cells.

Get a new battery, see how it goes,

Good luck
 
Sounds like your battery is shot.... Half the time when i used to take my batteries to those places they were wrong.... So i'm sure if you put a new battery in it then it will be fine.

Its really hard on a battery to let it sit for a bit of time, start it up, go a short distance then turn it off for awhile again....

If it doesnt even try to start after eight hours of charge, its not going to take a charge.
Just get a new battery and you should be ready to go......
