My car won't start

Negative. Not in all cases. If a battery has one or more cells growing sulphates between the plates, it can effectively reduce the voltage by 2 volts per cell. Even if the battery is not sulphated, yet allowed to sit for an extended period of time, the voltage can drop significantly. Enough to kick juice out to allow the gauges and dash to light up with 'key on', but not enough to light the starter, even a reduction gear equipped one.

So I get to my office early today and try to start the car. It kicks over immediately. The battery was a little weak probably from the 7 or 8 attempts at starting it yesterday. Ran it for about 10 minutes to charge up the battery. Will try starting it again at lunch time today.
So I'm still not sure what was wrong. If it was a battery, it shouldn't have started this morning either, correct? If it was a starter, perhaps it loosened up over night? I brought a rubber mallet to hit it but that wasn't necessary.
If it doesn't start up later, I'll guess I'll still have to have it towed.

Just started it again and battery back to full strength from running it. Of course everything is working again since I am planning to take it in.
Could the clicking sound when it wouldn't start be the starter solenoid?

I posted this in another post. Just because your battery has 12 volts doesnt mean the cranking amps are done. You have cold cranking amps that initially start the car. If they are KO then it wont be starting anytime soon.
You can always take battery in and get it tested. Will tell you if you have cold cranking amps. To me it sounds like battery.
This time of the year with heat and or cold can heavily effect your battery. Also if its not garaged. Temps get colder when exposed to winter and sun.

battery is losing juice! replace it as mine was doing the same thing.

Agree with SoCal, and 48k miles is sometimes enough time to use up a battery, especially if its the OEM battery. It happened to my wife's car in a parking garage one time and I ended up taking a new battery to the parking garage, installing it there, then we drove home...

Load test the battery and eliminate it from consideration. Sulfated cells might support turning the lights on and ringing the chimes, but as soon as you hit the starter, you need ~300A to get the starter turning. A sulfated cell might produce 2 or 3 amps just fine, but never full starting current.
Sitting overnight has lots of possibilities including the starter solenoid, but it still sounds like a weak battery or a loose battery terminal.
Jump starting does not always work if the battery is really flat. It might take a while to charge before you can even jump start. I have seen this many times.
