I'm 100% fed up with my car !!!!!!
I need a new battery no doubt , I just dont know why when I charge up the battery the trickle charger read 100% full and the volmeter read 13 volts if the battery were to be fried wouldn't it read like 3 or 5 volts instead of 12-13 ?. I took it to pepboys and they checked it and said the battery was fine.
Yes, that means the battery is fine if it is holding charge and you test it and it reads 12-14. Do what I suggested with the starter, see what that tells you. The clicking noise is one classic sign of a starter on its way out.
Thanks dude, I will do that for sure, anyways I'm getting a new battery so I have no doubts. If the new battery doesn't solve the problem I will check the starter like you said my friend.

Batteries can easily read the correct voltage and still be bad. The only way to really test a sealed battery is to load test it. A voltmeter doesn't do that and neither do most battery chargers.
Pep Boys should have performed a load test on the battery though and if they said it was fine then I'd say there's a 95% chance it is. There's a 5% chance they don't know how to test a battery correctly.
When a load simulating a car trying to start is place on a bad battery the voltage can drop dramatically. It might start off at 13-14 or whatever but drop to levels that won't operate the starter once it's loaded. No matter how low the battery gets if you test to see if current is going to the starter when you attempt to crank it you will get a reading. That is also not any kind of battery condition test.

Hook a batt charger/jumper up to the battery and see if you can start the car. A jump would work too. If it starts up then the batt is the cluprit, if not, narrow down the fuse/starter issues. I am still leaning towards the latter. Do you turn the headlights on, do they last long? bright?

i got the KAW battery cause its cheap, but ive heard nothing but bad stuff about it. mines hasnt failed me, but im pretty sure, if im out, i'll prob be stuck in the middle of nowhere with this battery
Take the alternator out and physically check the alternator. I had a similar problem and after changing the battery twice I found the alternator housing bolts (holding the alternator together) had come loose.
