Default My turn for the battery issue

I have a 07 GT that I took delivery on in Nov 06. It has just over 12k miles on it, garage queen. I was going to run over to wally-mart yesterday for a US Flag. Press the fob to open the door, headlights turn on, get in and turn the key and nothing. Release the clutch and push it in harder... Still nothing... more than nothing... nothing electrical is working right. Get my DVM out of the work van, 12.3Vdc at the battery. It should be more than that, right? Pull the covers off of the battery cells. Fluid looks OK. Connect the charger to the battery and let is cook for a short time. Still will not turn over. Came here to the good 'ol Mustang Forums and did a search of "battery" in this section. Guess the Factory battery is crap. Going to have to take some time off of work and get her towed to my local Ford dealer. I still have 5 months left on the warranty, that is if I do not extend it. It feels weird not being able to jump in the Mustang and go somewhere, yes I still have 2 other cars, but they are not the MUSTANG. fd

You may be able to avoid a towing charge if it can be jump started. But if it will not jump start, then something other than the battery may be causing the problem.
Also, if you have not already been doing this, always switch the stereo unit to the Radio mode when you're finished driving, and then turn the stereo off manually before turning off the engine. These cars are known to continue feeding power to the stereo if it's left on when the engine is turned off, which can reduce the battery's life.

Jump start it. No reason to pat a tow bill. I'd compare how much a battery will cost wi8th your warranty against a real battery like an Optima or Interstate.
I went with an Interstate.

No matter what the battery voltage is unloaded, have someone try to start the car while you are monitoring the battery voltage. If the voltage falls to less than 8-10 volts while attempting to start, it's a low battery. If it drops to almost zero, it's definitely the battery.

At least you have Ford's roadside assistance still so getting it jumped or towed won't cost you a penny!

I believe its the PATs system that wont let you turn it over.
Does the PATS indicator stop flashing when you insert the key
and turn it to the run position, not the start position?
