A good test to check the battery is to turn the headlights on and get someone to watch the brightness of the lights whele you try and crank - if they dim badly then it's your battery gone for sure.
If you have a multimeter you could check the battery voltage after the car has been sitting overnight - it should by 12.8V.....under 12.6 and it's suspect. You need to leave the car overnite to stabilise the battery voltage.
The clicking noise can also mean the solenoid on the starter is bad but first check the battery as it is cheaper and easier to fix.
